This will show you how to make a nail shooter out of a nail (whoa) and a rubber band.

WARNING~~ THIS IS EXTREMELY DANGEROUS. IM NOT KIDDING, THESE COULD CAUSE SERIOUS HARM TO SOMEONE. DO NOT SHOOT AT PEOPLE OR ANIMALS. (alive or dead)

Step 1: Get the Materials

You will need:

pliers (2 will make it easier to bend the nails)
rubber band (doesnt have to be thick, thinner ones are easier to use) its up to you
a pile of nails (I use ones that are about and inch long)

Step 2: Bend the Nail(s)

Bend the nails using the pliers. It makes it easier to hold if you bend it so there is more of the head end that is not bent. So its not quite center. Keep making them until you get bored or run out of nails. Whichever comes first.

Step 3: FIRE!!

Hold the rubber band between your thumb and forefinger, hold the nail in the other hand, pull back and release. IT WILL TRAVEL VERY, VERY, VERY FAST. Find targets (preferably inanimate objects) to fire at. This one was shot at a wall.
