Spud guns

I happened to cruise by one of the Biggies and saw that he posted a bit about a potato gun.

Ha! If he wants to propel vegetables through space he needs this website or this one*. Plus a google search brings up a bunch more of 'em.

*Disclaimer - I have seen several websites point out that ABS is the preferred material for a spud cannon. PVC can shatter if too much propellant is used.
