Hi all,

I came up with this idea after watching the mythbusters episode.I've already made the piston valve so if it won't work then i won't have gone too far in.

I am going to weld all the Metal tubing together.


It doesn't have to work extremely well its only very small more like a proof of concept type thing.A range of 7 feet or above is excellent.5 feet or above would be good.i dont mind how far it goes just as long as it goes further than a metre.

This is it only the main parts are labelled but everyone should get it.

I meant shoot it "old school" and just blow through it. :wink:


Then again, imagine a pneumatic with a 3" barrel and a 6" chamber firing 3" diameter spitballs.. Hmmmm *goes to draw up some plans..*

I just realize I have an untested steam cannon sitting in my back yard from last year.
On a semi-related note, does anyone know what I can use to contain molten salt? It eats through steel coffee cans like playdoe.

Would you use a spring to hold back the piston?
Why do I try to make a relevant post?

I have the same problem with flying salt. It eats through my popcorn like..air.

After thinking about that mythbusters episode, I couldn't help but think about how much fun a spud gunner would have in that warehouse. (Not the mention the budget somewhere in the thousands) :D

I found I could easily punch through a corrugated cardboard box using wet issue loaded in my 3/4" piston launcher, scary stuff.
