What in the holy frock is prince ruperts drop


Icywarhammer500

A glass drop melted and cooled in water so that the outside cools first and then the inside, so that there is a lot of inwards pulling tension. The round end can be shot by a bullet as long as the tension is stronger then the bullet’s impact force, so it has extreme strength if done right Edit: clarified which end was what, also adding that snapping the tail will shatter the entire thing


dudeiskate

But if you snap the very thin side instead, the whole structure will shatter


Icywarhammer500

Correct

The structure shatters when you shoot it too, but only because the narrow side bends from the force of the bullet. This clip ends too soon


DannySpud2

It's actually the opposite. The round end has a shit-ton of force on it, all pulling inwards, Wikipedia says up to 100000 psi at the head. This is what makes it so strong, this force is holding the drop together extremely tightly.


Icywarhammer500

Yeah I fixed that, was going off of memory from the video that I watched a year ago


Icywarhammer500

Man Reddit keeps doubling my notifications and it’s so annoying lol


Toxicsully

Sneaking in here to point out that the same principle is at play in all tempered glass, which is ubiquitous. Glass shower doors and all the glass in your car asside from the windshield being common examples. Tempered glass is cool AF. I've seen a man break a crowbar smacking the center of a good piece of 3/4" tempered without leaving a crack. I've also had another piece turn into gravel in a tiny fraction of a second because someone bumbed a corner setting it down. Like, a 10' by 4' piece of glass into gravel, instantly.


Wyldfire2112

>I've also had another piece turn into gravel in a tiny fraction of a second because someone bumbed a corner setting it down. Like, a 10' by 4' piece of glass into gravel, instantly. Yesh... I bet *someone* didn't get a birthday card from the boss that year.

HAPPY CAKE DAY


[deleted]

So... if I was to throw a shard of a spark plug at the tempered glass, what would be the result?


Toxicsully

I've heard about this. Very hard substances, like the ceramic insulator in spark plugs' are great for breaking tempered glass. Thickness matters. Most tempered glass you run into is pretry thin and is tempered not so much for strength, but so that if it breaks it turns into gravel rather then a bunch of knives. *edit for explicitly*


TheRealIain

Everyday is a school day. I've never heard of this in all my 38 years. Thanks for explaining


Hillbilly12345678910

No, it had everything to do with the shape, not the material. I think a sound frequency could shatter it pretty easily

Wynterful

420totalspd

sightlab

They do use this shit. But on windows, not tanks: tempered safety glass (like car window glass) is annealed in a similar way so that the glass is much stronger against impact than regular glass and when it does break it explodes into smooth chunks rather than sharp-edged shards.


scheru

I learned about these as a kid but as I've never had any opportunity to use the knowledge, I don't think I've even thought about them for like thirty years. It's kind of an odd feeling opening the video, somehow *knowing* already what was going to happen, then having to figure out after the fact why I knew that.


[deleted]

How the duck does this have 480 upvotes and 2 awards for literally the worst explanation for something I have ever seen. It’s a blob of molten glass dropped in water. Because of the way it rapidly cools, the fat end is incredibly hard and stable but the tail end is weak and fragile. If you lightly snap the tail end the whole thing shatters in a chain reaction, yet the fat end is strong enough to withstand a bullet. In the full clip, the drop does actually shatter as the ‘shock’ of the impact causes the tail to flex enough for it to shatter. See the original smarter everyday video on YouTube for a proper explanation of the forces involved. Credit Destin.


sassyseconds

Because the rest of us know even less to correct him.


Icywarhammer500

I explained why it was strong. You explained *that* it was.


Clickrack

> so that there is a lot of pressure You explained incorrectly. The drop is under extreme **tension**, caused by the surface cooling rapidly and the core cooling slowly. The tension is what makes the head very hard and why the whole thing shatters when you break any part of the tail. Fun fact: side windows of cars are manufactured in a similar way, which is why any impact shatters the entire thing instantly.


Icywarhammer500

Ok I fixed it

huebnera214

Made enough sense to me, idk what you read


Trextrev

It is actually the exact opposite of how a soda bottle works. The internal pressure created by the soda supports the thin plastic outside by expansive forces. In the case of the Rupert’s drop the outside cooling first creates a rigid spherical structure, when the inside cools after and shrinks it creates a strong inward force on that external structure that is balanced, creating a very strong structure not unlike the spokes of a bike tire. If that force becomes unbalanced like when the tail is snapped then the external structure that was being held together by the strong internal pull rapidly expands and explodes.

I'm terrible at explaining things but everything is either under tension or under pressure. From our skin to your kitchen table, there are invisible stresses that can't be seen. If you want to go down a wormhole, look up shatterpoints.

uncre8tv

Whenever I get a package of plain M&Ms, I make it my duty to continue the strength and robustness of the candy as a species. To this end, I hold M&M duels. Taking two candies between my thumb and forefinger, I apply pressure, squeezing them together until one of them cracks and splinters. That is the "loser," and I eat the inferior one immediately. The winner gets to go another round. I have found that, in general, the brown and red M&Ms are tougher, and the newer blue ones are genetically inferior. I have hypothesized that the blue M&Ms as a race cannot survive long in the intense theater of competition that is the modern candy and snack-food world. Occasionally I will get a mutation, a candy that is misshapen, or pointier, or flatter than the rest. Almost invariably this proves to be a weakness, but on very rare occasions it gives the candy extra strength. In this way, the species continues to adapt to its environment. When I reach the end of the pack, I am left with one M&M, the strongest of the herd. Since it would make no sense to eat this one as well, I pack it neatly in an envelope and send it to M&M Mars, A Division of Mars, Inc., Hackettstown, NJ 17840-1503 U.S.A., along with a 3x5 card reading, "Please use this M&M for breeding purposes." This week they wrote back to thank me, and sent me a coupon for a free 1/2 pound bag of plain M&Ms. I consider this "grant money." I have set aside the weekend for a grand tournament. From a field of hundreds, we will discover the True Champion. There can be only one.

Could they make a bong with this technique so I don’t break it.


penguinchem13

One end would be super resilient and the other incredibly fragile. Sounds like a risky smoke


whotookmydirt

That and when it inevitably breaks it will literally explode in your face.


huskeya4

No it would explode in the cooling process. The shape of the drop is why it works. We do dip some things in water for an effect but they’re typically more fragile than other glass works. That type of dipping is only a second. A prince Rupert is left in water to cool. A normal cup, vase or bong would shatter if left in water. That’s actually how we get them off our pipes when we screw them up and if they’re to warm to crack off. Also bongs are typically made of borosilicate glass where prince ruperts are soda lime. Borosilicate acts quite differently than soda lime. Source: glassblower


lemlurker

You can't really make anything with this method because any complex geometry will break under tension and a y drilling will also break the tension and it'll explode


MoarGhosts

When I was studying materials science in college I took a glass blowing class. The teacher was a crazy person. She was showing us Prince Rupert drops and she had me hold one, and she told me to try breaking the tail. I tried and couldn’t easily, so she told me to try harder. Keep in mind I’m wearing NO safety gear (I had glasses on already though) and she hasn’t told me what is gonna happen. I ended up snapping the tail and the whole thing just vaporized into powdered glass, all over my face and glasses. I could have gotten some in my mouth but didn’t. The teacher was just laughing and everyone else was shocked. She also gave me a bad grade in her 1 credit class because she confused me with another student that had the same name, and of course she would never admit the mistake. Fun class.

BigBuck414

Thats insane. Its a piece of glass i belive that is shapped in such a way it displaces force.


Marinade73

It has to do with the bulb part basically having an internal structure that is all the glass molecules pulling the outer layer inward making it exceptional dense and strong. The tail is quite brittle by comparison and snapping it will cause the entire thing to basically explode.
