Fuse Ignition Bomb -------------------- By: Lex Luthor A four strand homemade fuse is used for this. It burns like fury. It is held down and concealed by a strip of bent tin cut from a can. The exposed end of the fuse is dipped into the flare igniter. To use this one, you light the fuse and hold the fire bomb until the fuse has burned out of sight under the tin. Then throw it and when it breaks, the burning fuse will ignite the contents.
