Pretty much the same principle as pre-stressed concrete, only a different method to get the pre-stressing. Very cool stuff. Gorilla glass is so tough because of a similar principle.

Does that mean if I flick an iPhone's screen in the right spot I can make it explode?

That covered everything except for how it can be broken in the first place.  What's the deal with the failure point?  How far back on the tail does it have to be?

Presumably if you get back far enough the molten glass didn't have the thickness to create the chamber effect.  That would be my guess.

The GIS for "exploding Prince Albert" wasn't nearly as horrifying as I thought it would be. You've let me down, Saint Gorgor.

actually there's not necessarily a failure point as such. A lot has to do with thickness and shape of the tail part of the drop. If you squeeze it, then anywhere you can get into it will work. Course that's not the only way to make it fail, in that case failure will happen as the vibration in the glass hits a point where the stresses in the glass working against each other cause a failure in the outer layer at which point the whole thing goes boom. Though in that case where it'll happen depends on the shape and thickness of the tail and other factors.

SWEET! Going to fire up the raku kiln and make some!!!

This just makes me want to make a machine to pump out some of these all the same size to try as arrow heads.

actually, if you go check out his Yewtewb channel, the one about the physics of how/why cats (almost) always land on their feet was pretty damn interesting too.

Is this the way they make those unbreakable glass spheres? I saw someone bounce a fist-sized glass sphere off a concrete floor.

Yup.

This is useful because brittle materials (like glass and concrete) are significantly stronger in compression than they are in tension. Pre-stressed members are stressed in compression so that when they experience tension they are just reducing the pre-stress load and not actually applying tension to the material.

That sounds like it would be straight from the porno version of The Big Bang Theory.

With all due respect, I loved the whole book. The movie was OK, but I kept waiting and waiting for Hollywood to fark it up, and they finally did at the end.

How come when it shattered right in their faces there wasn't any damage to them?  They all seemed content to have the glass explode right next to their face while they only wore safety goggles.

From watching this guy and how he interacts with his kids and how his infectious curiosity drive him towards knowledge, I can set aside his personal irrational beliefs in invisible people if it makes him a better person. So few people calling themselves "Christian" actually are. This guy is in the Fred Rodgers class of Christianity: grace and kindness and love for others and wonderment of the world around them.

That is all good.
