Default Re: B: Aluminium powder(leftover from heatsink?)

piezoelectricity is the effect where mechanical energy applied to a certain type of crystal lattice is converted into high voltage AC. and ive done stupid things like this: one time i shot 20000 volts through a rocket engine, and the whole engine exploded in my face. the risk is not worth the fun. thermite will melt anything, so just think, if i put an object so hot that it will melt a whole in your floor in your hands....

You can buy anything you want there, every pyrotechnic powder...thermite...sodium metal, lithium metal, potassium, hydrochloric acid, nitric acid, sulfuric acid, etc etc. * Pretty much every chemical and metal you can think of they have. Its a great place to find neat stuff. i just recently got some sodium metal and some other chemicals for testings sake. Like gibberellic acid, which acts as a plant hormone and can cause plants and trees to become absolutely huge and mutated. ;D

I won't make thermite, to expensive for short time fun..

You need at least a pound thermite for each "good" charge.. Then for much dollers you have 10 charges.. not worth it IMO.

Can you make the pieze electric thing on your own?
