I recently had the idea for this new vacuum cannon design that many of you might be interested in. Since it hasn't been very long since my last vacuum cannon video I thought I would make this a more casual demonstration so I could ramble about all the various features and concepts without worrying about fitting everything into a script. If you would like to see my previous video of my 4" bore cannon you can check it out here: https://youtu.be/cDoUBJbyZ-8

Here is my video about making PVC pistons like the one used for this cannon: https://youtu.be/BCZGWvieJ7I

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.
