This was a fun project just before I started high school. My best friend John and I were looking for something fun to do at the end of summer. We settled on a pneumatic spud gun. The design is pretty simple, we used PVC pipe and a PVC valve. We used epoxy to seal in a valve stem and tested the ability to hold pressure up 100 PSI.
Next step, lock ‘n’ load a potato, or a golf ball, or a chunk of snow, etc. Brace yourself. And quickly flip the valve!
Our Spudinator was used to practice calculations on the trajectory of a ball in our High School AP Calculus class and later as a confetti cannon for our high school graduation.
