My cousins are coming to my family get together where the people have bonfires, food, and everything elseThey have a good timeTwo of my cousins never been camping and one tried it once and wanted to go home after 2 hrsI want to scare the crap out of them at 3 a.mANY IDEAS? I want to pull it off this coming Friday! I've thought of using exploding 2 Liter pop bottles (Aluminum Foil and The Works toilet bowl cleaner) ~My Fave~ that sound like a very loud gun going off and a stink bomb recipe (Ammonia and matches sealed inside a glass jar) :)Does the stink bomb potion work? I never tried it B4.
Copper/Aluminum/Titanium Alloy
Just remember, what goes around comes around.
Probably a high-strength aluminum alloy or titanium, though a metal playing card would be like a razor blade.
