Very cool video from an interesting channel in general. Destin does some great and unique experiments.

It won't let me embed two videos, but if you need a little background on the mechanism behind why this behaves the way it does, check out his earlier video:

Or this: https://en.wikipedia.org/wiki/Prince_Rupert%27s_Drop


The very high residual stress within the drop gives rise to counter-intuitive properties, such as the ability to withstand a blow from a hammer on the bulbous end without breaking, but experiencing explosive disintegration if the tail end is even slightly damaged.

That was actually pretty amazing. And now I know what a Prince Rupert drop is.

That is really cool. I love his channel.

The backwards bike is still one of the best videos he has done in my opinion.

That was a great video.

Does anyone else get a "TwangNBang" vibe from that guy?

I'm going to put together a bullet proof vest that looks like a chandelier to protect me from 22lr assassins.

Very cool.

Especially interesting was the shock wave traveled through the glass roughly twice as fast as the .22 LR impacted it.

He should have upgraded from .22 to .380 then 9mm then 45acp then 5.56 etc until he found one that would break it. Like how demo ranch does armor "tests".

Fascinating!

Sounds like this was step 1 in figuring out how to produce tempered glass.

And now I know why I see the pattern on some car rear windshields with polarized shades. You are actually seeing the internal stress. Very cool nerd moment.

If you look at his "gun", You'll see he is really not that into caliber selection.

Interesting vid. I had never even heard of a Prince Rupert's Drop before. At first it sounded like some type of bowel movement.
I want to see how it holds up to a .50 BMG.

Isn't this type of tension what is already used in Correlle and ceramic body armour?

Was wondering how long that was going to take.

Aaaaaaand I looked it up. Shit.

On topic...

Most interesting science thing I've seen in a long time.
