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.

Step 1: Parts

You will need:
1 bicycle pump (preferred foot pump)
1 bicycle tire stem
1 1/2" pvc threaded end cap
1 1/8"  brass nipple (1.5 to 2" long)
1 1/2" to 1/8" brass reducer

Step 2: Brass Connection

Do you have to do brass or can you do pvc

ryobi (author)screwscyco2011-12-18

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)?
