1. 1
   Get a ping-pong ball and wrap it in tin foil.
2. 2
   Poke a hole in the top of the wrapped ping-pong ball. Use a hobby knife, small screwdriver, a tooth pick, or ice pick.
3. 3
   Put two bricks a little bit apart on a non-flammable surface and gently wedge the ping pong ball between them (with the hole facing up).
4. 4
   Use a lighter to heat the bottom. This may take 5 to 10 seconds.
5. 5
   Back away quickly at first sign of smoke. Because the smoke is toxic and it smells bad. Run quickly and cover your nose.
6. 6
   This step is optional, as number 5 said, the smell is toxic. If you are afraid of holding it or if its in a windy situation you could use a fuse. Fuse could be bought in stores or you could create it from paper. To do it, you need to take a paper (size depends on your bomb), wrap 1/2 of the bomb using the paper but, if you wrap them all, the result is that it wouldn't smoke, but a huge fire. So, after folding it 1/2 of the bomb, you need to make a tail out of it. Now as usual, light up the tail. Yes it's slow but its better if you do this on windy days.
