Paper Towel Tube, Ball Gun

 For people who save up toilet paper tubes and paper towel tubes to make projects out of, these next few posts will be just what you need. For the first project, I will make a paper towel tube gun that shoots balls (make sure that the ball can easily go through a paper towel tube).

 Start by punching a hole through the paper towel tube (there should be one on each side).

 Then cut a nice long rubber band so it looks like a string.

 Put both ends through your holes and tie them together on the outside (don't cover up the open ends).

 Then cut a toilet paper tube in half vertically.

 (like this).

Then cut that in half (vertically).

 Glue one of the pieces into the open end that doesn't have the rubber band (this gives the ball more tension on the rubber band).

 (optional) while it is drying, you can tie a string to the rubber band so the rubber band doesn't get stuck in the middle of the tube every time.

 (like this). Then you will put the ball in the half of toilet paper tube and stretch the rubber band on it. Then, let go. (If the ball gets stuck in the tube, try to shorten the paper towel tube).
