Using the same concept as a potato cannon, you can create your own Christmas cannon with PVC pipe and a bicycle pump. Instead of loading the cannon with a potato, however, you use tinsel, confetti, or other Christmasy items.
You, or you and your supervised children, can learn how to make a Christmas cannon at the Instructables website. Not only would a Christmas cannon be a great hands-on science project for children, but it’s sure to provide hours worth of blastastic fun!
There’s only one downside to the Christmas cannon that I can see: the tremendous clean-up to follow.
