I'm looking for a scientific explanation of how this "confetti bomb
" prank works. It uses compressed air squirted inside a film canister, then quickly filled with confetti and sealed. After a few seconds, the canister explodes. Why?

I know they use an extremely cold liquid in compressed air containers, and holding the can upside down discharges the liquid. Air contracts when cooled, so the effect is actually technically an "implosion" of the lid being sucked into the film canister. Is this correct?
- What is the liquid in the compressed air container?
- Why does it squirt out as a liquid when the can is upside down?
- Why is this prank so much fun?
