A New Nerf War: The Pressure Gun

Have you ever thought of making your own cannon during a Nerf war?  Well, I recreated an invention that I made when I was about 8.  This invention is called the pressure gun.  It is very easy to make, however,  it is a hassle to load, and hard to fire long shots. All you need is paper,  those tubes you find with a paper towel roll, Duck Tape, and a gallon sized sealable bag.   Just cut a hole big enough for the tube, and seal the hole for the tube with the Duck Tape.  Now just blow a large amount of air into the bag from the tube, stick a crumpled ball of paper in the tube, and finally hit the bag so that all the air rushes out and fires the the paper.

**warning**   Do not aim at head or face.
