you can make one lol, all you need:
a gum wrapper
scissors
9 volt battery
small copper wiring (just some cheap, thin wire is all you need)
tape
stringy/shredded paper and some regular paper (preferably notebook)
a small tree branch (a nice and dry one)
fold gum wrapper in half (hamburger style) and cut from one corner of the crease (don't cut too much but make it as thin as you can) and you should have a little something like [refer to the image]
unfold and tape the wires t the foil side of the wrapper, wires should be on "fat" sides where it's not a crease
attach wiring to 9 volt battery (i promise this will not shock you, ik my electrical really well)
be careful, middle of wrapper will be VERY HOT!! use the middle of the wrapper and lightly touch shredded paper, and once you see a fire, then the fire will begin to blaze up. don't take too long bc the paper may burn up, but put the stick on the fire like a torch
ignite the bomb w/ the stick
