ok, i've built basic combustions out of some of the most random crap, such as beer cans, toilet paper rolls etc. has anyone ever made a cannon out of items they have found in a dumpster before? i managed to do it with some pringles cans, an old lighter, a popcan, a partial role of duct tape, and i used popcans as ammo. the only thing i couldn't find was the fuel which i later used. if anyone has done something similar id be interested to hear some stories.
peace,
Flinch
