Post your most Awesome stories/quick anecdotes of the ridiculous, dangerous and amusing escapades. If this gets Awesome enough, I will make a PDF and have it printed and bound in Book Form.

So one time, I decided it would be cool to go and make dangerous chemicals and incendiary devices. First up was Nitrogen Tri-iodide, a powerful contact explosive. (me and my friends were incredibly bored that summer) I wont post how to make it, out of respect to not getting NR sued, so instead here is Wikipedia's description of the stuff:

Nitrogen triiodide, also called nitrogen iodide, more correctly, triiodine nitride, is the chemical compound with the formula NI3. It is an extremely sensitive contact explosive: small quantities explode with a gunpowder-like snap when touched even lightly, releasing a purple cloud of iodine vapor. NI3 has a complex structural chemistry that has required relatively heroic efforts to elucidate because of the instability of the derivatives.

no, this stuff can be set off by a strong WIND, and here we were with about a half cup of the stuff. many bricks and old comp parts met their end that day... at one point, we were considering taking what we had left and putting it into a pringles can and throwing it, but we thought better, and continued to simply throw things AT the stuff, much safer than actually throwing it.

Anyhoo, we had fun with it.
Any other tales of irresponsibility and boredom in action?
