You will need: pool noodle, pom poms, balloon, scissors, and tape
You will need to cut the pool noodle, to pieces that are about 3" long. Then cut just a bit of the top of the balloon off. Tie a knot at the end of the balloon where you usually tie off a blown up balloon.
Slide the open end of the balloon over one end of the pool noodle, and then tape it down all the way around.
You will stick the pom poms in the open end of the pool noodle. Make sure you don't use pom poms that are to big because they will get stuck in the noodle and not come out. Then you pull the balloon back and then release and the pom pom will go flying.
See that green ball shaped item in the last photo that is the pom pom flying through the air.
