this is a small yet powerful(for what it is) canon that's easy to make and can easily fit in your pocket. great for school (don't get caught)
Step 1: Supplies Needed
1.piece of card board, pop-cicle sticks, etc. (anything for a surface)
2.a hollowed out pen tube
3.a pick-up stick, or the "pen" part of the pen tube
4.a rubber band
5. hot glue, or tape
Step 2: Putting It Together
1.glue or tape the pen tube to what ever small surface your using and glue or tape the rubber band about two inches from the back of the tube.
2.tape or glue the stick or pen part to the rubber band with most of the stick in the tube
3.let dry (if your using glue)
Step 3: Fun Time!
pull back stick, place an oblect down the front of the tube(my favorite thing to use are airsoft bbs), let go and have fun!
