The original, the best, the most effective... the glove gun!
Check out this weapons video tutorial to make your very own glove gun, which could be very dangerous if done right.
You'll need the following materials: A piece of pipe (plastic, PVC, cardboard, or metal), super glue, masking tape, the fingertip from a latex clove, and some pebbles.
This little glove cannon will shoot those pebbles as far as disbelief. Who needs pistols or firearms when you have this awesome glove projectile?
