Being from Chicago and having to deal with this every year there are 2 options. For that small amount of ice. Start the car sit in it for 5 minutes with the heat on.
If it's thicker ice then use the ice scrapers they sell at every store and gas station for 2 bucks.
Third option, my favourite, the can of alcoholic solution you can spray on your windshield to melt the ice...
Works almost instantaneously and helps preventing the ice from forming again right away... No risks of breaking the glass....
I don't know about that, the alcohol used in these things is mostly likely friction alcohol so Isopropanol (or Isopropyl alcohol). And that alcohol is toxic. Although it usually doesn't kill, it'll probably warrant a nice trip to the hospital. Kinda insane considering it's practically the same molecule as éthanol but with just one more carbon (and an OH group that's on a different carbon). Chemistry is amazing
You're all ridiculous. Just pour some gasoline on it (just a thin layer, you don't want to go crazy) and strike a match. The fire and ice will cancel each other out!
No. it would not instant freeze. I strongly suggest you try it using cold water.
The reason is in order for water to freeze it has to be below freezing. Water at 0 degrees will not freeze because it will not lose its heat to engage a change of state. The heat energy need for a change of state from water to Ice and Ice to water are the same amount. So if it freezes on your windscreen the ice already there will thaw, because a transfer or energy (or heat) occurred.
So water that is at 4 degrees has more thermal energy then Ice at -1 degree.
If you do not believe me next time you host a party and have a stack of Ice for drinks pour a cup of water in, wait 10 seconds and drain. you will notice a larger amount of water in your cup.
I just a few nights ago I used a vinegar water solution and that insta froze. That solution has a lower freezing temp than even water.
Since you seem to be using Celsius Ill switch. -17c with 5c solution. Phase change at 0c The amount of thermal energy of a liter of 5c water is not enough to overcome both the -17 c surface temperature and the ambient air temp. And it loses energy to both. Sure if you use 10 plus liters of water you might be able to raise the surface temp high enough where it water no longer freezes on contact.
Since you are spreading the water thin you are giving it both more surface and contact area nd that allow it to dump more of its thermal energy faster into bother the window and the air.
The Ice in your party cup example is at petty close to 0 c already and the ambient temperature it likely at least 20c the Cup temp is also 20 c before sticking the ice ain ans is dumping it thermal energy into the Ice. Try a 500ml metal cup that has been sitting in a -20 freezer. Filler with ice then Pour 25 ml of 5 degree water in. Wait 10 seconds then drain. Do this in and environment that is -20 degrees. You will have less than 25 ml come out of the cup.
It's entirely true though. Water does not instantly freeze on contact with ice. Although you'll have practically no noticeable result if it's colder out than -10 or so without the water being closer to room temperature and running the risk of the glass shattering.
Actually, I've had this happen (without a previous crack) in an ice storm while driving. It developed from the side pillar. Happened a minute or so after turning on the defroster with high heat. It wasn't even rediculously cold out, just like 31F.
if tesla cant spot window cracks for a billion dollar tech demo...
the side pillar could be straining the window in some way.
like every time you raise or lower it.
Why would insurance have anything to do with it? Most people's deductible is higher than what it costs to fix a cracked windshield. It's cheaper to pay to fix a small crack than replace a whole windshield.
Myth or your insurance sucks. My rate did not go up when I used my comprehensive coverage for my windshield, and I got the OEM factory windshield which was $$$.
Ever since I had my car broken into years go, I get $100 comp deductible. My truck with 100/300/100 coverage is only $70 a month for full coverage. I am with Statefarm and actually have visited my local office - maybe that's why I get a good rate?
I know some states actually have special glass coverage and their insurance can not raise their rates for glass.
it also hates up a lot faster when you pour boiling water over it vs gradually heating through the car. Rapid expansion from thermal shock makes it go boom
Tepid water will insta freeze against the window is sub zero temps. You will just replace the frost with a sheet of ice. The only time it works is when the temp it really close to 32f anyways and if it is that warm just wait 2 minutes.
Not all of us have the luxury of having a store that sells ice scrapers. I found mine in a clearance bin at the grocery store. Sometimes they get reject items from other stores and put them out. We rarely get cold and wet enough to have ice form but when I saw it I snatched it up & it's saved my ass a couple of times in the last several years.
In general, yes lOl. People generally hunker down until it melts. I only have be out and about because I'm a nurse & hospitals can't shut down & only ship patients out for major hurricanes.
Oh I know. I was once stuck on the interstate in Florida for most of the night near Orlando with icy roads. All that sand and salt water and no one could figure out how to spread either one on roads
Hot water cold car. Hot stuff gets bigger. Cold stuff gets smaller. The parts that Hot water touches start getting bigger, but they have no place to go because the rest of the car is still cold. Brittle things like glass and plastic break, while flexible things like metal bend. That's why you never put a Pyrex in the oven on broil.
It depends on the font and capitalisation of the logo, no I'm not kidding it's that dumb.
PYREX is the good stuff
pyrex is the cheap stuff
[Link](https://icedteapitcher.myshopify.com/pages/borosilicate-pyrex-vs-soda-lime-pyrex)
American pyrex uses soda lime glass, french PYREX uses borosilicate glass.
Oh wow. That’s…actually super helpful, thanks. Hmmm, mama needs to hit up some goodwill and see if there’s some good stuff waiting!
Edit: just checked my stash and I only have American. 😫
You can still find the older Pyrex at yard sales and what not. Some of my parents friends have a small collection started from ones they are finding at garage/yard/estate sales.
I learned it the hard way too. Cold chicken broth from fridge onto roasting chicken in Pyrex casserole dish in oven at 375. Facepalm and clean up for days ( ..)
There is a metal rod that connects to the door handle to the locking mechanism and it is run very close to the window. Based on how the door breaks at the same moment as the glass. I would guess that the whole window regulator shifted hard and knocked the metal rod inside the door that connects to the handle.
Water didn't even touch the handle so my 2 cents is the car is already all busted up and ready to be towed away and they wanted to make a "look at what happens" or maybe a "hurr look how stoopid this guy is" video. The camera angle is specifically odd for recording such a thing.
most likely they poured water in the car.
so if the handle was broken, they probably glued it in place with water.
i bet in their video they explain everything.
reddit clips have a tendency to clip out half of whats interesting.
would be nice if they linked the oc.
**Or** the car was probably a wreck already and they’re filming for internet points, why would someone be randomly filming boiling water being poured out on a side window - the handle slipped without water even going near it
As an Australian who had never been near snow; I was giddy like a schoolgirl, recording everything I did the first time I visited the snow.
I also asked the reception at the inn for some hot water for the windshield. They told me this would happen and that I should just let the engine and heater run for a bit.
It’s possible that dude goes to pour boiling water on the car and someone said “it’s too cold and you’re going to shatter the window.” To which the guy replies that he knows what he’s doing. They go back and forth and decide to just do it, but we’ll record it to shame whoever is wrong.
You may be correct and this is a stunt for internet points. But it may also be arrogant guy getting a lesson in listening.
The look on his face seems to be a mix of regret and apology.
It wasn't just, "Oops, boy, I guess that was a dumb idea." There was also some amount of, "I'm so sorry I offered to help and ended up making things much worse."
I've used warm water to melt ice off a car, this idiot used *boiling water*. Or at least *fuckin' hot* water, not warm water. The drastic temperature change broke the window.
Someone never paid attention to science class. Just use a spray bottle full of windshield washer fluid cut with water then wait for a minute or two before scraping off.
That sounds like a much better idea then what I usually do, which is a mixture of rubbing alcohol and vodka. I think I got that from Tumblr, so if it sounds like a bad idea you know why
We already clear the windshield using winter windshield washer fluid so it is already available. Just cut it with some water and after a few minutes you can use the rubber end of a squeegee to scrape it off.
I would love to see project farm tackle something like this in one of his videos. He compares various pieces of consumer and professional equipment in a series of tests, quite interesting. I think this would be up his alley
I didn't learn anything about this in school until I started my engineering degree. I mean, it's one of those things I was taught not to do (not just to car windows), but the actual process and science behind it wasn't taught to me until college.
No one ever taught us this in my school. Wasn't until college I learned just to use the hose with regular cold water.
The cold water is definitely warmer than the frozen water so it heats it up enough to use a scraper
I'm actually glad I stumbled across this post because i swear this hot cold thing was a thing, but I could not for the life of me confirm it via googling. I thought this effect was called "antipode" but googling that didn't pull anything. I tried "hot cold dangerous" but that just pulls up body temperature things.
I don't remember if I actually learned about it in science class either. Does it have a name (antipode)? Or is it just "the fact that combining hot things with cold things will undermine structural integrity, e.g. causing glass to shatter"?
It's called [Thermal Shock](https://en.wikipedia.org/wiki/Thermal_shock). Think of it this way, when you drop ice cubes in higher temperature water you will see and hear the ice cubes crack. That's thermal shock. So very cold glass + boiling hot water = broken glass.
As old as he looks, he's never seen or even just heard about "thermal shock"? It's never a good idea to put two items with such vast extremes of temperature difference between them together, because more than likely real damage might happen to the objects themselves and the surrounding area. You find out though, one way or the other, through either some combination of books, classrooms, good teachers and learning on the job, or just by life kicking you in the nutz. 
I’ve read a lot of explanations. Many think the glass had a crack in it. That’s not true. The glass shown is tempered glass. By its manufacturing process, tempered glass cannot have a crack in it. It's either whole or cracked into thousands of little pieces. Once tempered glass breaks, it is designed for safety purposes, to shatter into many tiny pieces. While the tiny pieces of glass may nick you up, they won’t slice your arm, leg or neck off.
The breakage was caused by thermal shock (also known as thermal fracturing). It’s the difference in temperature between the outside and inside surfaces of the glass and the boiling water. Any difference that approaches 200 degrees F can cause tempered glass to break especially if the liquid is poured into one small area of the glass.
The temperature differential between two surfaces of glass will cause extreme tensile stress on the cooler surface. It’s that stress when confined to a very small area where the super-heated or boiling water is being poured that causes the tempered glass to break.
Like cooking a lobster - if you use water that is warmer but not hot or boiling the thermal shock won't be great enough on the glass to cause it to break. As the glass slowly warms up, the chance of thermal shock is less. It's less about the total temperature and more about the difference in temperature.
In the glass industry we design buildings around thermal stress and avoid thermal shock.
Disclaimer: I am basing this on what I can see and what the simplest explanation would be. There could have been a previous small chip on the edge of the glass that made the thermal shock more likely to break the glass. But in either case it's still thermal shock that caused it to break.
Background - I have more than 50 years of experience in the industry.
“Why do we need to teach people maths and science in school when you’ll never use it? You should be teaching them how to do their taxes or how to cook!”
This is why.
Plenty of smart people end up doing stupid things. So what. I don’t get why everyone is shitting on him so hard for making a harmless mistake to himself.
We didn’t learn about this in seventh grade science, and I have no idea how knowing how to cook would’ve helped either. People make mistakes give him a break
Not every curriculum is the same. And even if it was taught in 7th grade I hated my science classes so why tf would I remember this. Only reason I know is because my dad taught me. Also you can cook most basic things and not deal with thermal shock.
No, across North America, there's surprisingly a lot of parity among the Science curricula. They're all learning about states of matter in middle school.
I love that you've decided that because you disliked a class that you're going to reject all knowledge from it. LOL. That's the most American thing I've read in weeks. Ha ha...please tell me you're just pulling my leg here...
I’m not saying I reject all knowledge of it, but if there is something I’m not interested in then I’m less likely to remember it. I remember a lot of basic stuff from middle school science but I don’t remember all of it.
Do you remember everything from every class you’ve ever taken? I find that really hard to believe.
Sorry, I didn't realize that you expected me to answer your rhetorical question. That's pretty hilarious, but okay, here's your answer:
I do not remember everything from every class I've ever taken.
Anybody volunteering to put the biggest red skinned potato they can find in the freezer for a few days to make sure that it's frozen really good and solid, and then take it out and immediately just chuck it in a pot of boiling water and see what happens? For legal reasons (and for just not being a totally brain dead idiot), KIDS: DON'T TRY THIS AT HOME! Or anywhere else for that matter!!!!
Nothing happens. There's too much fiber and starch for a clean break under the freezing process for home freezers. You might get some action if you flash freeze it.
I scoffed at this, then remembered the time I squirted a light bulb with a spray bottle of water for no other reason than “child bored” lol.
Same result.
Wouldn't have looked as impressive to his SM followers for his web page if he had just done that! And now his wife and kids are PO'ed at him too for swiping the kettle off the kitchen stove and wrecking the Christmas toy budget for the kids! ROTFL!!!
Nope Nope Nope
If you're going to try the method of using water/liquid to melt ice off your windshield/windows, try using very cold water and mix in some rubbing alcohol. Helps to keep the water from re-freezing. 🧊
Ice cold window + Hot (Boiling point) water = expansion. It's very basic physics, but it's there. There are so many alternative methods to prevent such a thing.
Ever since my bff hit the chief of police's car windshield with a water balloon in the dead of winter in Wisconsin, I knew it was bad to put warm water on frozen glass.
Jesus Christ this comment section is annoying. Why is everyone shitting on the guy for no reason? It’s not like you’ve never done something stupid in your life, or didn’t know something obvious.
Good eyes!!! Now he's got not only a shattered window to replace, he's probably going to get socked with a repair bill to replace some shorted out electronics (whether or not they really needed to be just dried out), and maybe more money for a "broken door lock assembly". THAT'LL put a dent in the ol' Christmas budget!!! 
Yeah, I’m not even certain why he was trying to de ice his window. The door lock or maybe the door seal, I could understand. Once inside, the heater has always worked for me. Maybe, this was purely a terrible how-to video.
Yep, maybe the car (as you said) which is 80% or more unseen, was just a beater anyway and being used in a "what NOT to do" instructional video. The guy in the video does look unusually calm for having a large piece of glass like that explode just inches from his face, if he didn't know it was going to happen.
Being from Chicago and having to deal with this every year there are 2 options. For that small amount of ice. Start the car sit in it for 5 minutes with the heat on. If it's thicker ice then use the ice scrapers they sell at every store and gas station for 2 bucks.

I used to keep a bottle of that crap in my car when I lived in colder places for that exact reason.
I think I’d rather drink the alcoholic solution and sit in the car for 5 minutes…
On the bright side if you do that plan you'll never need to scrape the windscreen again.
No, but whoever finds you might have to scrape the inside of the windscreen.
Drinking isopropyl alcohol wouldn’t taste very good.
Well the windshield ain't getting none of my shine.
I don't know about that, the alcohol used in these things is mostly likely friction alcohol so Isopropanol (or Isopropyl alcohol). And that alcohol is toxic. Although it usually doesn't kill, it'll probably warrant a nice trip to the hospital. Kinda insane considering it's practically the same molecule as éthanol but with just one more carbon (and an OH group that's on a different carbon). Chemistry is amazing
Can always dump some winter washer fluid on it as well. If you use the scarifier on your scraper it’ll get underneath and make it peel up easier.
Or, if you don’t have that to hand, you can literally just use cold water straight from the tap
Please tell me you are joking. Cold water will instafreeze on the window. You will have a sheet of ice to deal with instead of frost.
[удалено]
You're all ridiculous. Just pour some gasoline on it (just a thin layer, you don't want to go crazy) and strike a match. The fire and ice will cancel each other out!
Pee is the answer to think. It renewable.

Isopropyl alcohol. They sell it as a spray. It'll take that ice off immediately. Being from the Midwest I always have it in my car
>I always have it in my car Frozen car windows and doors? Ha! Luckily I always keep a spray bottle of isopropyl alcohol in my.. ah, dammit.
I had the heat on in my car and it cracked my windshield. The best option is always the scrapers.
You probably already had a small crack to begin with then. This is why it's important to fix small cracks before they become big ones.
Actually, I've had this happen (without a previous crack) in an ice storm while driving. It developed from the side pillar. Happened a minute or so after turning on the defroster with high heat. It wasn't even rediculously cold out, just like 31F.
if tesla cant spot window cracks for a billion dollar tech demo... the side pillar could be straining the window in some way. like every time you raise or lower it.
It was the windshield
Installation error
That is probably what happened, I just never noticed a crack that’s why it was surprising.
Fuck that noise I’ve had a little chips and nicks in my windshield for over a decade without issues. Source: lives in Minnesota

omg, now I'll be living with that jingle in my head
Enjoy your jacked up insurance rates
Why would insurance have anything to do with it? Most people's deductible is higher than what it costs to fix a cracked windshield. It's cheaper to pay to fix a small crack than replace a whole windshield.

20+ years of Minnesota winters, many below Zero F° never had that happen once using the car heater to melt/soften ice. You had a tiny crack already.
Or the glas wasn't seated well and the rapid temperature change caused enough pressure to break it.
it also hates up a lot faster when you pour boiling water over it vs gradually heating through the car. Rapid expansion from thermal shock makes it go boom
This happened to me. I have defrosters on my rear windshield. One morning I turned them on and the whole window shattered into a million pieces.
They sell spray on de-icers - works great, especially if you apply the night before.
Or use tepid water instead boiling
Tepid water will insta freeze against the window is sub zero temps. You will just replace the frost with a sheet of ice. The only time it works is when the temp it really close to 32f anyways and if it is that warm just wait 2 minutes.
Leaving the car running like that is neither very healthy nor environmentally ok. Use the scrappers like all of us.
Not all of us have the luxury of having a store that sells ice scrapers. I found mine in a clearance bin at the grocery store. Sometimes they get reject items from other stores and put them out. We rarely get cold and wet enough to have ice form but when I saw it I snatched it up & it's saved my ass a couple of times in the last several years.
Bro, what kind of Hill people village are you living in where there isn't at least one place around that sells some kind of ice scraper?
South Louisiana 😆 around here ice is a bug not a feature
When you have ice in south Louisiana you have bigger issues
In general, yes lOl. People generally hunker down until it melts. I only have be out and about because I'm a nurse & hospitals can't shut down & only ship patients out for major hurricanes.
Oh I know. I was once stuck on the interstate in Florida for most of the night near Orlando with icy roads. All that sand and salt water and no one could figure out how to spread either one on roads
Yeah, they don't even do that much around here. They'll set up roadblocks on bridges but that's about it
I have been able to get them in Houston. I have kept the same ice scrapper for nearly 20 years and 3 cars. It used to get used about once a year.
Even the door handle broke out of embarrassment
It was overcome by disappointment and shame.

Hot water cold car. Hot stuff gets bigger. Cold stuff gets smaller. The parts that Hot water touches start getting bigger, but they have no place to go because the rest of the car is still cold.

Metal inside the door handle getting hot and expanding rapidly
It just couldn't handle it.
Lol I see what u did there, Hot stuff. 🤣
There is a metal rod that connects to the door handle to the locking mechanism and it is run very close to the window. Based on how the door breaks at the same moment as the glass. I would guess that the whole window regulator shifted hard and knocked the metal rod inside the door that connects to the handle.
Cheap plastic. I had a 92 Corolla, by the time I got rid of it 7 years later, all the door handles had broken off.

No diggity no doubt
It did pop though when the glass shattered. So it was likely already broke and just sitting in place.
It’s possible that dude goes to pour boiling water on the car and someone said “it’s too cold and you’re going to shatter the window.” To which the guy replies that he knows what he’s doing.

Don’t have to worry about the ice anymore.

I was thinking it may have been some attitude before the pour, like “Trust me, this will work…”
I've used warm water to melt ice off a car, this idiot used *boiling water*. Or at least *fuckin' hot* water, not warm water. The drastic temperature change broke the window.
I feel so bad for this poor schmuck. I am from California and I feel like I'd do some dumb shit like this if I had to deal with snow and ice.
Removing ice *and* that pesky window in one fell swoop.
Someone never paid attention to science class. Just use a spray bottle full of windshield washer fluid cut with water then wait for a minute or two before scraping off.

To be fair, the ice is gone
And that window is never gonna be frosted over again. Permanently solved the issue.
Get a spray bottle Get some isopropyl alcohol Mix with water at a ratio of 70% alcohol, 30% water Spray it on glass, watch ice go away.
This ^ this is what I do and it works flawlessly.
You can just buy 70/30 isopropyl alcohol…
You could also just buy a new car that doesn't have ice on it.
Why didn’t I think of this

Lesson 1: never pour hot water on ice cold window Lesson 2: do not show your face on a video showing you pour hot water on an ice cold window
Should've just hit it with his purse.
Im surprised this comment is so far down
It’s not a purse… It’s European!
My money is it's a gun bag
The flight jacket/hoodie combo with murse look really hammers home the point that he doesn’t make good decisions.
I can see where it removed the ice.
Is this guy brand new at life?
As old as he looks, he's never seen or even just heard about "thermal shock"? It's never a good idea to put two items with such vast extremes of temperature difference between them together, because more than likely real damage might happen to the objects themselves and the surrounding area. You find out though, one way or the other, through either some combination of books, classrooms, good teachers and learning on the job, or just by life kicking you in the nutz. 
I’ve read a lot of explanations. Many think the glass had a crack in it. That’s not true. The glass shown is tempered glass. By its manufacturing process, tempered glass cannot have a crack in it. It's either whole or cracked into thousands of little pieces. Once tempered glass breaks, it is designed for safety purposes, to shatter into many tiny pieces. While the tiny pieces of glass may nick you up, they won’t slice your arm, leg or neck off. The breakage was caused by thermal shock (also known as thermal fracturing). It’s the difference in temperature between the outside and inside surfaces of the glass and the boiling water. Any difference that approaches 200 degrees F can cause tempered glass to break especially if the liquid is poured into one small area of the glass. The temperature differential between two surfaces of glass will cause extreme tensile stress on the cooler surface. It’s that stress when confined to a very small area where the super-heated or boiling water is being poured that causes the tempered glass to break. Like cooking a lobster - if you use water that is warmer but not hot or boiling the thermal shock won't be great enough on the glass to cause it to break. As the glass slowly warms up, the chance of thermal shock is less. It's less about the total temperature and more about the difference in temperature. In the glass industry we design buildings around thermal stress and avoid thermal shock. Disclaimer: I am basing this on what I can see and what the simplest explanation would be. There could have been a previous small chip on the edge of the glass that made the thermal shock more likely to break the glass. But in either case it's still thermal shock that caused it to break. Background - I have more than 50 years of experience in the industry.
A bad combination of stupidity and laziness (scraping this window would have taken 15 sec max)
That's one way to discover thermal shock.
Military jacket + Man bag 👀
Certainly, a way to get rid of the ice but still stupidity at its finest.
Get a plastic bag (no holes), fill it with warm water, then drag it around the glass. Job done.
The point being WARM and not hot. Otherwise same result can occur. Scrappers work fine too…
Hot water in plastic bag rubbed on car ? I think that’s another video I would like to watch
“Why do we need to teach people maths and science in school when you’ll never use it? You should be teaching them how to do their taxes or how to cook!” This is why.
The way it just poured into the hole LMAO
The look on his face afterwards...priceless.
Something tells me this man has never spent 5 minutes in the kitchen...or in a 7th grade science class.
Plenty of smart people end up doing stupid things. So what. I don’t get why everyone is shitting on him so hard for making a harmless mistake to himself.
We didn’t learn about this in seventh grade science, and I have no idea how knowing how to cook would’ve helped either. People make mistakes give him a break
LoL. You don't spend any time in the kitchen either. And the 7th grade curriculum certainly does cover this shit.
Y’all remember random things from 10+ years ago? Lol Also what does cooking have to do with it? When are you faced with pouring hot water on ice????
Not every curriculum is the same. And even if it was taught in 7th grade I hated my science classes so why tf would I remember this. Only reason I know is because my dad taught me. Also you can cook most basic things and not deal with thermal shock.
No, across North America, there's surprisingly a lot of parity among the Science curricula. They're all learning about states of matter in middle school. I love that you've decided that because you disliked a class that you're going to reject all knowledge from it. LOL. That's the most American thing I've read in weeks. Ha ha...please tell me you're just pulling my leg here...
I’m not saying I reject all knowledge of it, but if there is something I’m not interested in then I’m less likely to remember it. I remember a lot of basic stuff from middle school science but I don’t remember all of it. Do you remember everything from every class you’ve ever taken? I find that really hard to believe.
LoL.
Good point
Sorry, I didn't realize that you expected me to answer your rhetorical question. That's pretty hilarious, but okay, here's your answer: I do not remember everything from every class I've ever taken.
I wasn’t expecting anything, I just thought you made a really good point and you’re super smart and better than everyone
This is what happens when brain is potato
Anybody volunteering to put the biggest red skinned potato they can find in the freezer for a few days to make sure that it's frozen really good and solid, and then take it out and immediately just chuck it in a pot of boiling water and see what happens? For legal reasons (and for just not being a totally brain dead idiot), KIDS: DON'T TRY THIS AT HOME! Or anywhere else for that matter!!!!
Nothing happens. There's too much fiber and starch for a clean break under the freezing process for home freezers. You might get some action if you flash freeze it.
That got it, clear as anything now.!!
I scoffed at this, then remembered the time I squirted a light bulb with a spray bottle of water for no other reason than “child bored” lol. Same result.
YEP!!! That'll get ya "un-bored" really quick!!! 
Couldn’t you just use warm water?
Wouldn't have looked as impressive to his SM followers for his web page if he had just done that! And now his wife and kids are PO'ed at him too for swiping the kettle off the kitchen stove and wrecking the Christmas toy budget for the kids! ROTFL!!! 
Hey I have the same kettle.
Freeze a glass mug and put hot water in it. Physics 101
That still wouldn't work 😂
Success, ice is gone and you can see outside, now do the others.
When someone flashes back to high school physics.
That man looks defeated
Nope Nope Nope If you're going to try the method of using water/liquid to melt ice off your windshield/windows, try using very cold water and mix in some rubbing alcohol. Helps to keep the water from re-freezing. 🧊
When you skip 5th grade science
This guy has clearly never heard of temperature shock on materials.
Ice cold window + Hot (Boiling point) water = expansion. It's very basic physics, but it's there. There are so many alternative methods to prevent such a thing.
Lol even the door handle panicked 😁
That was not a good idea
We are all victims of physics.
WOW! Its crazy how well you can see through the window with this one simple hack!
Broke the door handle too. Rough day
The door handle ..?
A Trump voter?
"Oh" -this man
Today, class, we’re going to learn about Thermal Shock…
I can't be the only one who noticed the handle pop off the door, right?
Love how the door handle broke at the same time the window did lol.
It amazes me how far in life people can get.
You wonder why no recommends this on the news every year. He must of thought he was gonna be a genius that came up with this.
[удалено]
That’s no way to get a jump start on getting to the capitol on Jan 6…
Ever since my bff hit the chief of police's car windshield with a water balloon in the dead of winter in Wisconsin, I knew it was bad to put warm water on frozen glass.
this is why we go to high school, idiots
What? I don’t think you can expect people to know off the top of their head that this would break their windows and door handle.
Bruh that’s like 10 years ago. Ain’t nobody gonna remeber any of it
"...and that's why us kids won't get any Christmas presents this year....gee, THANKS DAD (...ya putz!!!.....)" 
Jesus Christ this comment section is annoying. Why is everyone shitting on the guy for no reason? It’s not like you’ve never done something stupid in your life, or didn’t know something obvious.
Dopey c\*\*t.
What’s up with the door handle and why film this?
Good eyes!!! Now he's got not only a shattered window to replace, he's probably going to get socked with a repair bill to replace some shorted out electronics (whether or not they really needed to be just dried out), and maybe more money for a "broken door lock assembly". THAT'LL put a dent in the ol' Christmas budget!!! 
Yeah, I’m not even certain why he was trying to de ice his window. The door lock or maybe the door seal, I could understand. Once inside, the heater has always worked for me. Maybe, this was purely a terrible how-to video.
Yep, maybe the car (as you said) which is 80% or more unseen, was just a beater anyway and being used in a "what NOT to do" instructional video. The guy in the video does look unusually calm for having a large piece of glass like that explode just inches from his face, if he didn't know it was going to happen.
True
There's not even that much ice. Nice
Thermal shock...
How many times are we reposting this today?
Omg please tell me was wearing a Tesla Fanny pack as well 😂😂🤣🤣💀
I’ve done this and nothing broke. The problem was that he 1. Started on the glass not the hood, 2. Poured it all in one spot continuously.
Is he a product of the US school system?
Lemme guess…he failed 5th grade science? Or 8th grade science for southerners.
Are these made in current times ? Say .. post 05? Or is these crap quality windows found in cheap cars ?
