Smash the bottom out of a bottle bare handed

Bill Beaty is our favorite kind of science teacher.

Here he gives us a lesson in cavitation. Sounds boring, right?

Ha! Not when he teaches us a wild trick to illustrate this physics phenomenon!

Bet anyone holding a beer bottle that he can't break it using only his hands. Secret: the smash only works when the liquid is NOT carbonated. So, make sure to fill your bottle with water before making the wager.
