This weapons video tutorial will show you how to make an easy homemade explosive sparkler bomb with ordinary household items.
You'll need some ordinary sparklers, and aluminum soda pop can (or similar object), a button battery (this is optional, but makes it explode), and a pair of scissors.
Cut the top of the can, break up the sparklers into the tin can, leaving one sparkler for the fuse, and then put the watch battery in the Coke can.
This cool sparkler bomb will give you years of enjoyment, or minutes if you don't like it. See the can light up on fire, exploding before your very own eyes, eyes hopefully wearing safety glasses, that is.
