hahaha, yours shouldn't be so eh... explosive as ours was. we just used really fine aluminium powder, usually you put it in a ceramic pot and molten iron shoots out the bottom through the little hole. edit: i could also give you a good place to buy the shit to make it, just pm me | ||

But as far as science fair. Physics > Chem >>Biology imo. | ||
