This video tutorial will show you the gist of making a cheap penny bomb. Cheap? Of course it's cheap. It's a freakin' penny, a cent, an Abe Lincoln, 1/100 of a dollar... it's cheap.
But wait, you also need some gun caps and tape. Take all of the black powder out of the caps and combine them with a few pennies. Tape them up and throw that sucker on the ground for a nice little bang for your buck... I mean cent.
This little penny bomb is cooler than you might think. Just watch this how-to video as the smoke explodes on the ground, sending shivers down your spine.
