KA-FUCKING-BOOM.. i go back and look the glass is blown in half.. my mate was pissed.. cos well.. it was his home it happened at.. still funny as fuq

Smooth containers do not have bubbles of air clinging to their sides. Rough walled or scratched containers may hold microscopic bubbles in their cracks. These become nucleii for boiling. Even a crack that is fully filled with water can be a boiling nucleus because it reduces the required area of the water-vapour surface.

Don't microwave cd's either...but it is really cool if you do, big blue sparks come out.

while on subject of microwaves n shit

if ur microwave is all stinky and got bits of crap n shit stuck to inside, get a bowl of water, chop up half a lemon and plonk it in microwave for 2-3 min, all the citrus juices makes it smell nice and works well as a effective de-greaser
