They should post a video of the hole process, loading/vacuum being done/then fireing. What a odd concept! But from the pics, it looks like it works. Cool beans, is this guy a member? Probly not, we would have seen this alot sooner.

I saw this on instructables a while ago... I would rather build a big piston gun.

indeed, why build something like that when you have spuds :D

But it is a nice science project though

I built one of those with my wet-dry vaccuum... fairly powerful, I knocked the cap off of a waterbottle with an acorn
