Pop Gun Home

My friend Bruce Yeany has made a pop gun video with a good idea about the sealing material.

There is a lot of great science in a popgun. A person building and using on has to grapple with atmospheric pressure and sonic compression waves.

I'd like to know how this project goes for you. I'm happy to answer questions about it. Feedback from you is an important way for me to know what works and what needs clarification.
