How to Make a Large Bore Vacuum Cannon

In this video I show how to make a large vacuum cannon with a 4 inch bore. Vacuum cannons are a classic science experiment used to demonstrate atmospheric pressure, though very rarely are they made as large as this. My ammunition is 3 inch PVC end caps, and atmospheric pressure is the only force responsible for firing them. See my earlier video for how to build a manual vacuum pump: • How to Make a Vacuum Pump • If you are not one of my Patreon supporters and would like to help my channel to improve check out my page and please consider contributing here: / nighthawkprojects • Special thanks to my top Patrons!
