How to Make a Quad-Barrel Air Cannon

Video Description

You've seen the demo, now learn how to make your very own semi-auto or full-auto R0M4 quad-barrel air cannon! Welcome back recruit! Major Sergeant Private Major here again, ready to help you create your very own multi-barrel pneumatic launcher! I'll go over the version from the demo video, as well as several others that we've created so that anyone can build their own ROM4. No soldering or coding experience? No problem! We've included a design that uses simple buttons and wire nuts. Join me. *** DISCLAIMER ***: As mentioned in the video, PVC IS NOT DESIGNED TO HOLD PRESSURIZED AIR. When PVC fails, it fails catastrophically (ie. it explodes). This can cause serious injury or death. I do not claim that building a cannon like mine (even by following my directions exactly) will mean you are safe using it. THERE IS NO WAY TO MAKE PVC 100% SAFE WHEN IT IS PRESSURIZED WITH AIR. If you choose to build this project, you do so at your own risk. I do not accept any responsibility for any/all damage, injuries, or death related to your building or use of a similar device. Check your local laws before making an air cannon, as some cities, counties, and states do not allow them. --- Parts/tools I used --- As an Amazon Associate I earn from qualifying purchases through links in my descriptions and comments.
