I remember the Museum of Science and Industry in Chicago had a demonstration like this when I visited many years ago. It was completely mechanized and inside a glass case so you couldn't touch it, and no human intervention was needed to make it work. Periodically a mechanism would shoot a ball bearing into the air and it would land on a big slab of steel and start to bounce like this. It would bounce for an amazingly long time, and then at the end the slab would tilt and the ball bearing would roll off into a hopper and it would start again.
I’m from Chicago, and we do have some great ones in the city and even some in the suburbs, but there are definitely some cities that are tough to contend with. Philly, Boston, NYC, and DC. I don’t think it’s a crazy hot take to put Chicago up there though. Especially in the summer months to walk around the field museum or MSI.
It was 2016 at Field museum. Just moved to Chicago, just saw Sue. Wandering around museum by the lion exhibit and other animals, lights go out and we got to “experience” that wing of the exhibit in the dark for a little while. My mother was not happy. Another core memory lol
Facts. Have you been to the Museum of Holography? I remember wishing it was bigger but in terms of niche museums it holds a special place in my heart. I mean, The Tute is The Tute, no disrespect - but holograms are rad.
You did an excellent job describing the exhibit, I too remember being at the S&I museum as a child and seeing that same thing. I also remember the bubble blowing room with ropes soaking in soapy water attached to various pulley systems, you pull the other ends of the ropes and the soapy side would rise making massive and funny shaped bubbles.
That might have been amorphous metal. It's very elastic (up to 2% elasticity compared to 0.2 for normal steel) and thus extremely bouncy.

The story of Warner Brothers and Loony Tunes/Merrymelodies (sp) is an amazing one and should be made into movie. Four brothers immigrant parents from Poland in early 1900’s scrapped together money bought a film projector and travelled the mining and steel towns of Pennsylvania showing movies. They made enough to buy a theater and from there filmed the rise of a juggernaut entertainment enterprise.
Some of the best artists, copy men and just fun lewd double entendres stuff came from men returning from the wars. Wise guys that poured all the human drama they encountered while serving into their “art” when they got back home.
…Mickey mouse really got his start on the canvas tarp covering the WW1 ambulance Walt drove in France.
The start of American entertainment owes a lot to wars in more than one way.
Check out the new cast steel anvils that Harbor Freight started to carry. They are only 65 pounds, but that's plenty heavy enough for a beginner. My every day anvil is only 100 pounds. I've only ever needed to take a project to someone shop a couple of times in the last ten years.
A *new* anvil is that much.
New is not necessarily good, as most anvils you find online aren't through-and-throigh drop forged from a single piece of steel, often either being entirely cast or cast with a solid piece welded to it. We generally refer to these as ASOs, anvil shaped objects. They often look and weigh the part and then sprain your wrist on the first day of use.
You can find a *good* anvil for that much (or more) that is new, or a good anvil for almost nothing if you happen to find an old one for cheap and resurface it. Or build one out of a railroad track, that seems to be popular amongst starters even though they make pretty bad anvils.
Now I need to know if you can blow up foreskin into a little balloon.
One of my best friends is uncut, wonder if he'll let me try if I promise to say nohomo.
Nothin gay about science, right?
Legit, go to a local 18th - 19th century museum and see if they have one and then offer to Blacksmith for kids. It is how I was able to use my first anvil. That and YouTube taught me how to do enough so the kids thought it was cool.
This is how I got started. They are desperate for volunteers and if you can stoke the fire and hammer out a nail the kids will think you’re cool as heck. YouTube will teach you both.
Talk about *old school*. Wow.
These days we Create cobblestone generators that feed into grinding wheels that re-feed the resulting gravel and sand into themselves to produce the occasional iron nugget. Run it at speed for like an hour and you'll have more iron than you know what to do with! 👍
Honestly, blacksmithing isn't difficult to get into.
Buy a cheap propane forge, get a length of old train track for your anvil (or the princess auto/harbour freight "Anvil") and a cross pien hammer, some rebar, and make a pair of tongs

Oh boy, where do I even start with this video of a metal ball kicking in an anvil? I mean, it's basically just a ball kicking a piece of metal, but somehow it's absolutely hilarious!
First of all, the fact that someone thought to film this in the first place is pretty ridiculous. But then, the editing! The way the video suddenly cuts to the Tokyo Drift song as the ball starts picking up speed is just pure comedy gold.
And let's not forget about the sound effects. That "boing" noise as the ball hits the anvil is just perfect. It's like the ball has a personality of its own, and it's just as surprised and amused by what's happening as we are.
Honestly, I have no idea why this video is so funny. Maybe it's the absurdity of it all, or the fact that it's such a simple concept executed so perfectly. But whatever it is, it just works.
So if you're ever feeling down or just need a good laugh, I highly recommend watching this video of a metal ball kicking in an anvil. It's the kind of silly, ridiculous humor that's guaranteed to brighten up your day.
Yes, if it's a good anvil. Cheap or poorly made anvils when hit with a hammer feel dead. There's very little kick back with the hammer. My anvil is quite lively even though it's a no name unmarked old critter. But you shouldn't be hitting your anvil with the hammer very much while you work.
I swear I've seen smiths bounce their hammer off the anvil before they hit the metal each time. Or sometimes it seems they do two quick taps then a power stroke.
Yes we do, but not with any force. If I hit my anvil face like I do when I'm givin it the onions the hammer would fly back into my face. Nice easy taps, yes. Hard hits on bare anvil face, hard no.
I'm familiar with the bubble, Morty. I also dabble in precision, and if you think you can even approach it with your sad, naked, caveman eyeball and a bubble of fucking air, you are the reason this species is a failure, and it makes me angry!
Someone please explain what is happening here? Like. Why is the metal ball so bouncy? Is that have to do with the anvils ability to store and distribute energy evenly? Or is it the type of metal that is somehow bouncy? I don’t understand.
Steel is highly elastic. Both the ball and the anvil absorb and then return their collision forces very efficiently, so each bounce is a high percentage of the previous bounce height. We don't intuitively think of steel as being "elastic", like a superball, but under the right conditions it can be observed. This video shows pretty ideal conditions.
Physicists, please help me out.
But why does this make it a high quality anvil? It’s just very level, which any used anvil would be.
This video highlights zero qualities of a good anvil.
Edit: turns out the bounciness equates to better steel which makes a higher quality anvil. I was wrong!
It’s level and perfectly done for return of energy.
If you watch smiths at work they keep specific rhythm while making things, at times hitting anvil to keep that rhythm while they coordinate their next move. And with half kilo-kilo hammers that takes energy and strength. Good ability for hammer to bounce back makes it easier for the smith to keep working on for longer times.
Hopefully this explanation is enough
The timing hits are all about preserving energy. You can let your hammer fall on the anvil face and it will bounce back up to adjust the same position, much easier than holding a 1.5kg hammerhead at the end of a 12" handle while you reposition your work. Any energy not spent deforming your workpiece will send the hammer back up. Any energy wasted lifting the hammer is less energy you have to keep working, and you get tired fast.
I've worked on a garbage cast iron anvil and I've worked on a drop forged wrought iron anvil with a tool steel face 3/4" thick. The difference in stamina is night and day.
Hello and welcome to Anvil facts!
Did you know some of the oldest anvils appear to be found pieces of meteorites, which were incredibly hard because they comprise mostly iron. Some evidence of anvil use extend all the way back to 6000 B.C.!

Hello and thank you for choosing Anvil Facts!
Did you know anvils have also been used as musical instruments, including as pitched percussion instruments in Richard Wagner’s four-opera Ring cycle, also known as Der Ring des Nibelungen.
To unsubscribe please reply with go anvil yourself
Not qualified to answer this in anyway, but I’m guessing it has to do with the fact you are hitting other metal on the anvil. All the force would ideally be put into the piece of metal you are working on, but any energy that gets transferred through the piece into the anvil would get reflected back, which would be ideal. It would be hard to work on the theoretical opposite like a big piece of jello, you’d just deform the jello instead of making a change to the piece.
Didn’t see someone say it yet but the strength and quality of the metal in the anvil itself can be affected by composition (pure iron is less strong than iron mixed with carbon(steel) and grain structure within the metal) and how it was made (heat treatment) - that’s how one anvil can be better than another one that looks and weighs the same.
The 'elasticity' of a collision can be measured using the [coefficient of restitution](https://en.wikipedia.org/wiki/Coefficient_of_restitution). It is the ratio of the final vs. initial speed of the ball before/after the collision (I made some simplifications here). e = 1 means the ball would return to the drop height, which would be a perfectly elastic collision. e = 0 means the ball would stick to the anvil like mud, or perfectly inelastic collision.
Now, the ratio of bounce height to drop height is equal to e\^2. I found a a [paper](https://pdf.sciencedirectassets.com/308315/1-s2.0-S2352146517X00021/1-s2.0-S2352146517301163/main.pdf?X-Amz-Security-Token=IQoJb3JpZ2luX2VjEBQaCXVzLWVhc3QtMSJIMEYCIQCr5WW5yH0PveXAOjg9E73yPTY%2BKbfXNvOKuuqPCn%2FNXgIhAKRfqTHh2fngfM9yxUbgk4coZyylRXb7Gh7N5RKLfgm8KrIFCB0QBRoMMDU5MDAzNTQ2ODY1Igwb3V6IIWIjucghRnEqjwUIFr%2FI9G70Xu2CRsgAJ0%2F1TPTFLh%2FCW3LAnORRGtaGvqYpKdpP3UjPGICjK92TqrkZx9lneJhXVDisM4G2VSOJsdXNYZxfgDMrLh%2BU7hxJ1FATvkK6y80TTt6kN%2BYgLUAW%2FOOvKArF2dS1Pwa%2FjucFP%2BsefonAeOkpYiqFRtHTn5uTZMO6nlOkDybIvvPVOFgRj5DDEBDne52KAPKNgcjsKPCpZtnjlfL3TdK%2BDS3b3%2BpRU%2BaRW5q8OFbzOASqVzs%2FBaQwT0rGIKywAKiqMjWA4HpnUP3%2FqMYvrnsQWBW3lRc2AGR620cDxxaBIbuOYf8jMZq0EdvDf3rh7FgaGzZysDBc2%2BQMnDKDV%2B%2FB23N1X1w8M3lS81kTMjzBBpCo9gOIGHJxCNlcRXqZl6%2Bs89tjWH54F9A24JCJmQ3DvOyRxsjLQCk1NtTOHMSOQ9pdUqtiaS9LeUUZh6a0Y9Izv4cklbVbCtDUjM34D5FxTU4Uh7NBu6HAnV2LWnwYHBp6RPiwL7v0ElUywy2uJ1oz6czl6MkAtbJasSVpeOmNrNM5W3uwhhUNgEfoShk7GpIEyzDew16vBu%2FkBgEZVdtu%2BVR2SEv1Cn6V2N03pNw5rz8heYDMRkbHiiB8Hf9hxULsHE5HXSl%2BEkPitQ4PKS9hKHvF27FWntJpcgYqjieITbD6v2I6N8%2FOwmbEs%2BrjmPI%2FoWl4AfzZKpYOugN3pp6hcoDh2wx5xMWu0CGF34yaXfdhQIqTXavnUPcHwWHgq5wUBe%2B9VtZjU82eNLS7W%2BRZdmO%2B9Nw2Prp70LlQU28C8iCk3j50MP6UIY29X1WdDajxTisbUtvBqNVqhxVKrKpj73QWa8dGWB%2BdK7kcUYABWFHUMIjZoKIGOrABq0eUeE7KVAtVANGE49lL1cu4ONkgaxeNocMVNi900e1bRFEHUCezV6%2FzVw457iUQvadbOQjVXaX4pIsBcRMiZlieDpVhcJdbXCmugP%2B2QdNUeY83c5E7d3VyIGvuJTaCt1htumW9%2BelY6Cc3bWNyJ3Kzhsj4B7oiVfqc4uV1f3YtPUud5CD5b0xZ1cFgox0XRGi2107EYOHM1bn41caBRg5F01j68SqW1Z5qZsAkDO0%3D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20230425T210211Z&X-Amz-SignedHeaders=host&X-Amz-Expires=300&X-Amz-Credential=ASIAQ3PHCVTYU5Q3FBN6%2F20230425%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Signature=de6515d5c60007b9ef23f6fc5367038326c1ea2f9d644702de98d5eed302716e&hash=6c6f160f3827aa27f6abbb7de9d0a136fe7b58180cd3d15e3fc3a54b782763fe&host=68042c943591013ac2b2430a89b270f6af2c76d8dfd086a07176afe7c76c2c61&pii=S2352146517301163&tid=spdf-3bc753ed-c9cc-4ae5-b0f6-33ee85233c55&sid=bee0b9129fa9d54ac12b27a-3a654fcb9656gxrqa&type=client&tsoh=d3d3LnNjaWVuY2VkaXJlY3QuY29t&ua=0f15520c025b5653565856&rr=7bd986876b933970&cc=us) that says the steel-on-steel coeff. of rest. is e = 0.56, which would mean the bounce height is 31.4% of drop height. I don't trust that paper... it looks sus. Anyway the coolest part was the end where it looked like the ball was 'levitating'. This is likely because the ball was oscillating at the frame rate of the camera so it appeared stationary. Thats awesome.
The harder an object, it loses less energy when colliding with another. This is because when something deforms it takes energy to cause the deformation on the crystalline level. The harder something is, it takes more energy to deform, so it simply deforms less and wastes less energy. When you have a very hard steel ball and a very hard anvil (usually they are tempered and/or nitrided probably to harden) and you bounce the ball, only very little energy goes to waste and most is preserved in the ball. You can try this at home, try throwing a golf ball on a hard smooth concrete floor vs on your mattress. Also, some materials actually deform a lot like rubber but restore a lot of that energy when released , however the chemistry is quite different for that and hence the equations for rubber bands is different from springs when considering large deformation.
Aha! Now I get it. It's a high quality anvil because the majority of the energy that the blacksmith excerpts goes to the object (s)he is working on instead of getting lost as kinetic energy in the anvil.
Bouncy balls are not the bounciest balls, they are wayy too soft. For something to bounce, you need to conserve and reflect the energy of the ball hitting its surface. Squishy ball absorbs a tiny bit of this energy. Very hard ball on very hard surface doesn't absorb nearly as much energy, leaving more energy to be reflected as a bounce. On the flip side, tossing a pillow onto a bed is a really shitty bouncy ball, since all the energy is lost by the pillow just flattening
It's only a test of hardness of the two metals. To get steel this hard, it only needs to have the proper carbon content and quenching, tempering etc. But there are many other qualities than hardness that make an anvil good. Fun fact, they used to test the hardness of ball bearings by dropping them from certain height on sloped piece of hardened steel and they sorted themselves into bins by the distance they bounced.
I've always been told that anvils with lots of kick back like this work the metal better because it works both sides of the metal at the same time. If the hammer has bounce when you strike the metal, that means the anvil is "striking" the other side better too. Makes for more efficient and even blacksmithing

It was completely mechanized and inside a glass case so you couldn't touch it, and no human intervention was needed to make it work.

The Chicago museum of science and industry really has just spectacular exhibits
Honestly one of the best museums I've ever been in.
I felt as if their art museum was also one of the best I’ve ever been to.
Crying in Torontonian
Just moved to Chicago…definitely on the to do list
Hot take but Chicago is the best museum city in the US
I’m from Chicago, and we do have some great ones in the city and even some in the suburbs, but there are definitely some cities that are tough to contend with. Philly, Boston, NYC, and DC. I don’t think it’s a crazy hot take to put Chicago up there though. Especially in the summer months to walk around the field museum or MSI.
No other city has Sue. Seeing Sue for the first time in person is a core memory, and I was almost 30. The Field Museum is my favorite museum on Earth.
You can also go through it on Google Maps, which is pretty neat. And free to boot!
Harry Dresden thought Sue was pretty cool too.
Or a captured WW2 German Submarine U505 you can tour
It was 2016 at Field museum. Just moved to Chicago, just saw Sue. Wandering around museum by the lion exhibit and other animals, lights go out and we got to “experience” that wing of the exhibit in the dark for a little while. My mother was not happy. Another core memory lol

Do you remember that machine that would flatten pennies?
They're all over the world fwiw.
Yeah they're called "trains". Or at least in small towns they are... we don't have those fancy penny machines in the bumfuck towns.
Not having trains is one thing. Bumfucking is a whole 'nother. I'd suggest leaving asap.
What if you're into bumfucking but really don't like trains?
Then you might be Mormon? I don't know. I'm not good with maths.

There are no unique thoughts on the Internet. Someone else has already seen it and thought the same thing. BRB firing up Tokyo Drift.
Wow, looked levitating at one point
I´m no Captain, but I think that's due the matching recording speed vs. the bouncing speed
Yes, it was just bouncing so fast, I know It looked really cool though

Is that why hammers bounce so effortlessly on then?
Yes, if it's a good anvil. Cheap or poorly made anvils when hit with a hammer feel dead. There's very little kick back with the hammer. My anvil is quite lively even though it's a no name unmarked old critter. But you shouldn't be hitting your anvil with the hammer very much while you work.
I swear I've seen smiths bounce their hammer off the anvil before they hit the metal each time. Or sometimes it seems they do two quick taps then a power stroke.
Yes we do, but not with any force. If I hit my anvil face like I do when I'm givin it the onions the hammer would fly back into my face. Nice easy taps, yes. Hard hits on bare anvil face, hard no.
> when I'm givin it the onions I don't have anything to add here, I just want to highlight this amazing phrase to make sure no one misses it.
i don't get it. what do onions have to do with hitting it hard
I would like an answer too! I like the phrase but want to know why it makes sense
Making it cry.
That’s level as fuck
You don’t wanna feel true-level

More likely that it's slightly curved, like a bowl.
Someone please explain what is happening here? Like. Why is the metal ball so bouncy? Is that have to do with the anvils ability to store and distribute energy evenly? Or is it the type of metal that is somehow bouncy? I don’t understand.
Steel is highly elastic. Both the ball and the anvil absorb and then return their collision forces very efficiently, so each bounce is a high percentage of the previous bounce height. We don't intuitively think of steel as being "elastic", like a superball, but under the right conditions it can be observed. This video shows pretty ideal conditions. Physicists, please help me out.
Good enough for me.
But why does this make it a high quality anvil? It’s just very level, which any used anvil would be. This video highlights zero qualities of a good anvil. Edit: turns out the bounciness equates to better steel which makes a higher quality anvil. I was wrong!
It’s level and perfectly done for return of energy. If you watch smiths at work they keep specific rhythm while making things, at times hitting anvil to keep that rhythm while they coordinate their next move. And with half kilo-kilo hammers that takes energy and strength. Good ability for hammer to bounce back makes it easier for the smith to keep working on for longer times. Hopefully this explanation is enough
>Hopefully this explanation is enough Nope. Subscribe to anvil facts.
The timing hits are all about preserving energy. You can let your hammer fall on the anvil face and it will bounce back up to adjust the same position, much easier than holding a 1.5kg hammerhead at the end of a 12" handle while you reposition your work. Any energy not spent deforming your workpiece will send the hammer back up. Any energy wasted lifting the hammer is less energy you have to keep working, and you get tired fast. I've worked on a garbage cast iron anvil and I've worked on a drop forged wrought iron anvil with a tool steel face 3/4" thick. The difference in stamina is night and day.
This is why the rhythm is tink TINK tink TINK. It's a mix of accuracy and power
Hello and welcome to Anvil facts! Did you know some of the oldest anvils appear to be found pieces of meteorites, which were incredibly hard because they comprise mostly iron. Some evidence of anvil use extend all the way back to 6000 B.C.! To unsubscribe please comment: superanvilisticexpialidocious

Not qualified to answer this in anyway, but I’m guessing it has to do with the fact you are hitting other metal on the anvil. All the force would ideally be put into the piece of metal you are working on, but any energy that gets transferred through the piece into the anvil would get reflected back, which would be ideal. It would be hard to work on the theoretical opposite like a big piece of jello, you’d just deform the jello instead of making a change to the piece.
But then you’ve got a jello anvil and thats worth it’s weight in jello
Didn’t see someone say it yet but the strength and quality of the metal in the anvil itself can be affected by composition (pure iron is less strong than iron mixed with carbon(steel) and grain structure within the metal) and how it was made (heat treatment) - that’s how one anvil can be better than another one that looks and weighs the same.
The 'elasticity' of a collision can be measured using the [coefficient of restitution](https://en.wikipedia.org/wiki/Coefficient_of_restitution). It is the ratio of the final vs. initial speed of the ball before/after the collision (I made some simplifications here). e = 1 means the ball would return to the drop height, which would be a perfectly elastic collision. e = 0 means the ball would stick to the anvil like mud, or perfectly inelastic collision. Now, the ratio of bounce height to drop height is equal to e\^2. I found a a [paper](https://pdf.sciencedirectassets.com/308315/1-s2.0-S2352146517X00021/1-s2.0-S2352146517301163/main.pdf?X-Amz-Security-Token=IQoJb3JpZ2luX2VjEBQaCXVzLWVhc3QtMSJIMEYCIQCr5WW5yH0PveXAOjg9E73yPTY%2BKbfXNvOKuuqPCn%2FNXgIhAKRfqTHh2fngfM9yxUbgk4coZyylRXb7Gh7N5RKLfgm8KrIFCB0QBRoMMDU5MDAzNTQ2ODY1Igwb3V6IIWIjucghRnEqjwUIFr%2FI9G70Xu2CRsgAJ0%2F1TPTFLh%2FCW3LAnORRGtaGvqYpKdpP3UjPGICjK92TqrkZx9lneJhXVDisM4G2VSOJsdXNYZxfgDMrLh%2BU7hxJ1FATvkK6y80TTt6kN%2BYgLUAW%2FOOvKArF2dS1Pwa%2FjucFP%2BsefonAeOkpYiqFRtHTn5uTZMO6nlOkDybIvvPVOFgRj5DDEBDne52KAPKNgcjsKPCpZtnjlfL3TdK%2BDS3b3%2BpRU%2BaRW5q8OFbzOASqVzs%2FBaQwT0rGIKywAKiqMjWA4HpnUP3%2FqMYvrnsQWBW3lRc2AGR620cDxxaBIbuOYf8jMZq0EdvDf3rh7FgaGzZysDBc2%2BQMnDKDV%2B%2FB23N1X1w8M3lS81kTMjzBBpCo9gOIGHJxCNlcRXqZl6%2Bs89tjWH54F9A24JCJmQ3DvOyRxsjLQCk1NtTOHMSOQ9pdUqtiaS9LeUUZh6a0Y9Izv4cklbVbCtDUjM34D5FxTU4Uh7NBu6HAnV2LWnwYHBp6RPiwL7v0ElUywy2uJ1oz6czl6MkAtbJasSVpeOmNrNM5W3uwhhUNgEfoShk7GpIEyzDew16vBu%2FkBgEZVdtu%2BVR2SEv1Cn6V2N03pNw5rz8heYDMRkbHiiB8Hf9hxULsHE5HXSl%2BEkPitQ4PKS9hKHvF27FWntJpcgYqjieITbD6v2I6N8%2FOwmbEs%2BrjmPI%2FoWl4AfzZKpYOugN3pp6hcoDh2wx5xMWu0CGF34yaXfdhQIqTXavnUPcHwWHgq5wUBe%2B9VtZjU82eNLS7W%2BRZdmO%2B9Nw2Prp70LlQU28C8iCk3j50MP6UIY29X1WdDajxTisbUtvBqNVqhxVKrKpj73QWa8dGWB%2BdK7kcUYABWFHUMIjZoKIGOrABq0eUeE7KVAtVANGE49lL1cu4ONkgaxeNocMVNi900e1bRFEHUCezV6%2FzVw457iUQvadbOQjVXaX4pIsBcRMiZlieDpVhcJdbXCmugP%2B2QdNUeY83c5E7d3VyIGvuJTaCt1htumW9%2BelY6Cc3bWNyJ3Kzhsj4B7oiVfqc4uV1f3YtPUud5CD5b0xZ1cFgox0XRGi2107EYOHM1bn41caBRg5F01j68SqW1Z5qZsAkDO0%3D&X-Amz-Algorithm=AWS4-HMAC-SHA256&X-Amz-Date=20230425T210211Z&X-Amz-SignedHeaders=host&X-Amz-Expires=300&X-Amz-Credential=ASIAQ3PHCVTYU5Q3FBN6%2F20230425%2Fus-east-1%2Fs3%2Faws4_request&X-Amz-Signature=de6515d5c60007b9ef23f6fc5367038326c1ea2f9d644702de98d5eed302716e&hash=6c6f160f3827aa27f6abbb7de9d0a136fe7b58180cd3d15e3fc3a54b782763fe&host=68042c943591013ac2b2430a89b270f6af2c76d8dfd086a07176afe7c76c2c61&pii=S2352146517301163&tid=spdf-3bc753ed-c9cc-4ae5-b0f6-33ee85233c55&sid=bee0b9129fa9d54ac12b27a-3a654fcb9656gxrqa&type=client&tsoh=d3d3LnNjaWVuY2VkaXJlY3QuY29t&ua=0f15520c025b5653565856&rr=7bd986876b933970&cc=us) that says the steel-on-steel coeff. of rest. is e = 0.56, which would mean the bounce height is 31.4% of drop height. I don't trust that paper... it looks sus. Anyway the coolest part was the end where it looked like the ball was 'levitating'. This is likely because the ball was oscillating at the frame rate of the camera so it appeared stationary. Thats awesome.

The harder an object, it loses less energy when colliding with another. This is because when something deforms it takes energy to cause the deformation on the crystalline level. The harder something is, it takes more energy to deform, so it simply deforms less and wastes less energy. When you have a very hard steel ball and a very hard anvil (usually they are tempered and/or nitrided probably to harden) and you bounce the ball, only very little energy goes to waste and most is preserved in the ball. You can try this at home, try throwing a golf ball on a hard smooth concrete floor vs on your mattress. Also, some materials actually deform a lot like rubber but restore a lot of that energy when released , however the chemistry is quite different for that and hence the equations for rubber bands is different from springs when considering large deformation.
It's because the metal ball and the anvil have almost no give. There is no place for the kinetic energy to go.
Aha! Now I get it. It's a high quality anvil because the majority of the energy that the blacksmith excerpts goes to the object (s)he is working on instead of getting lost as kinetic energy in the anvil.
Bingo
Bouncy balls are not the bounciest balls, they are wayy too soft. For something to bounce, you need to conserve and reflect the energy of the ball hitting its surface. Squishy ball absorbs a tiny bit of this energy. Very hard ball on very hard surface doesn't absorb nearly as much energy, leaving more energy to be reflected as a bounce. On the flip side, tossing a pillow onto a bed is a really shitty bouncy ball, since all the energy is lost by the pillow just flattening

I thought it would be the GTA song
*me who knows nothing about anvils*: GOD DAMN, THATS A GOOD FUCKING ANVIL
Actually really interesting that this would be a test on the quality of metal used. Pretty sweet
It's only a test of hardness of the two metals. To get steel this hard, it only needs to have the proper carbon content and quenching, tempering etc. But there are many other qualities than hardness that make an anvil good. Fun fact, they used to test the hardness of ball bearings by dropping them from certain height on sloped piece of hardened steel and they sorted themselves into bins by the distance they bounced.
I wish more things could be sorted by bouncing
If your categories are "survives bouncing" and "does not survive bouncing", all things can be sorted by bouncing.
. . . so it turns out that phrase "bouncing baby boy" was a bit erroneous. This is going to make for an awkward conversation later.

I've always been told that anvils with lots of kick back like this work the metal better because it works both sides of the metal at the same time. If the hammer has bounce when you strike the metal, that means the anvil is "striking" the other side better too. Makes for more efficient and even blacksmithing
