The Mini Spud Launcher launches tiny bits of potato. The good thing about this project is it is all under $5. This project is small but it gets about 18-20 feet of range.

Do you have to do brass or can you do pvc
ryobi (author)  screwscyco2 years ago
The brass screws into the pvc end cap so you would probably need to use brass.
Not to be mean or anything... but...
this isn't a spud gun
A spud gun uses combustion of usually air freshener in a chamber to propel it out
If it is using air pressure, it is called a pneumatic airgun, and no launching potatoes does not make it a spud gun
Good job though :D
U can use pvc as well but dont put the pressure too high, plus, I dont think People make 1/8" PVC

there is no valve the the potato launches when it is ready (you can add a valve if you want to).

This sounds like a lot of fun! Where's the valve (how do you release air into the chamber)?
