An occasional column....
1. A empty quarter litre Coke bottle (or any other PET/plastic fizzy drink bottle)
2. Quarter litre of liquid nitrogen
3. A metal dustbin full of hot water
1. Fill the bottle with the liquid nitrogen
2. Screw the top on. Hard.
3. Drop it in the metal dustbin full of hot water
4. Run away. Fast.
Alternatively, you should go and watch this lunatic do it for you.
