:lol: And I thought my old dry ice bombs were bad!
We used to put a slack handful of pelletized dry ice (frozen carbon dioxide for those that don't know what it is) into 500ml - 1000ml fizzy drinks bottles and then fill them about a third full with warm water. The dry ice pellets would then vigorously begin to sublime, effervescing considerable amounts of gaseous CO2...Then you screw the top on (as fast and tight as you can) and casually put them wherever.
You usually have about 15 seconds to a minute (depending on bottle size, pressure resistance etc.) before they detonate. A good, strong bottle creates quite a concussion!
To get an idea of the pressure involved (theoretically, that is), a good handful of the stuff (wearing gloves of course!) would be around 44g (1Mol), which can expand to 22.4 litres of gas. Inside a typically 1/3 full 500ml bottle, you could theoretically get 67 atmospheres (940psi) of pressure. I expect they bang a good time before then.
Especially good fun in a bucket of baked beans left outside someone's door ;-)
