NOTES: We take absolutely no responsiblity for what you do with this bill of materials or anything you make based on this bill of materials. Assemble at your own risk.
⚠️ Use the thing that you assembled at your own risk. The CO2 cartridge should be empty before connecting it the brass fittings. If you have one that's already empty, great! If not, you'll need to break the seal on the CO2 cartrige to empty it.
☠️ When you drain the CO2 cartridge, it will release a lot of CO2 at once, which will make the cartridge get really really cold (liquid becoming a gas). Wrap it with a towel before you break the seal so you don't freeze burn your hands.
When connecting the On/Off Valve, make sure to follow the in/out labels on the valve.
Be careful with how much air pressure you charge up in the chamber. You can rip a hole in your nerf bullet if you try to launch one with too much pressure.
