i made a more impressive but complex form of that. i pumped a small balloon within a waterbottle and tied it off. then i poked a hole in the cap with a metal dart. then i took a pump and pumped the bottle until it was at 60-70psi (don't go to 80 it will burst) hold the hole with your thumb tightly so the air can't be released. allow the balloon to travel down towards the cap and release the pressure. the balloon will stop the air flow and you can pop the bottle with extreme power.
