MythBusters need to bust this one. Oh wait...

mmmmmm... watermelon-pizza-sauce-dirt-covered candy!

(also I assume bareboards2 has not seen a single episode of Mythbusters)

My initial suspicion was the same as the host's - that the bottle was rocketing up and the cap was "overrun" by the rest of the bottle. That doesn't hold up to scrutiny since the cap "shrinks" back rather than staying still.

In their first explosion, the cap actually explodes very quickly after the burst. That seems relevant. I'm not sure how.

My second thought is along the "vacuum\low pressure" line of thinking. The entire bottle is pressurized in the instant of the explosion, and then ruptures at the bottom, so now the bottom of the bottle is lower pressure as water is rushing out, pulling the cap end down. Bernoulli principle, perhaps?
I imagine a bottle full of water, but it has no bottom. The water is rapidly and forcibly evacuated. The logical thing is for the cap to be crumpled downward.

Ooh, wait. Could this have something to do with the gas at the top of the bottle vs the liquid? I'm having flashbacks to the Mythbusters episode about the sinking car, and how the pressure of the water inside the car was lower than the outside as long as significant amount of air was left in the vehicle, so even though the water was up past the inside of the car door, it still couldn't be pushed open until the rest of the car had equalized. This seems relevant to me as well, though I'm not sure how, exactly.

There's equally square tires on your sense of humor.

I was curious as to what myth this was debunking...

Turns out it's whether at a certain speed a square wheel could ride as smooth as a round one.

I love Mythbusters and I enjoyed the clip, but the show should really be called Answers to Questions Nobody's Asked + Explosions!

for all the algebraphobes

I like this guy! They did this on Myth Busters too.

Yea, but our leadership is giving Christians an education in the incentive program.

^Yet the great thing about living in America is that we don't lose our minds over something like that.
Purely for comedic effect, no one is going to start a riot over it like we have seen others do in other parts of the world.
