The Sparkler bomb.
I made one last independence day. I didnt think it would work, but it was quite suprising.
All i did was..
Buy about 10 packs of sparklers (The silver ones, not the paper-wrapped ones)
Take out all of them, make sure you have at least 20, or more.
Get strong tape, duct tape is best.
Wrap them all up as tight as you can get them, leave one sparker protruding out the top about 2 inches, to use as a fuse.
Light it and stay away.
This is NOT going to make one giant sparkler, me and my friend put it in a bucket, and it shot a fireball out the top of it. Gladly, we werent close to it. So when you light this bomb, do not put it near something expensive, or your friends.
