Question

im going to make one =]

Answer 1

take 6 pop cans cut both end off all of them, except for one leave the bottom on and poke a hole in the bottom. tape them together by sticking them in one into the other till you get a long tube. now you need a potato and some lighter fluid. pour the lighter fluid in the hole and shake the tube till the inside is all coated in it. put your potato in the tube and light it ..      I never used potatoes but rather a duct tape ball.
