Check out my previous video to learn how I made the cannon valve used in this project: https://www.youtube.com/watch?v=G1VCZEXi384 A big part of how I've been able to keep making videos on YouTube over the last year is thanks to Patreon supporters. If you enjoy these projects please consider contributing on Patreon and you'll get some other cool stuff like early access to videos. Most of all your support will mean I don't have to rely on the volatile YouTube ecosystem to keep this channel afloat, and new videos will be assured no matter how bad YouTube messes things up in the future.
