Yeah, manufacturing a firearm requires a license in Germany, and a firearm is “a device that propels a projectile through a barrel”…

Then again, any university with a physics department can get these licenses easily, since many devices used for high-speed impact testing/research fall under the above definition.

Is the soda bottle being used as a pressure release?

Pressure builds until it explodes pop bottle, then the projectile fires?

The guy loading isn’t the sharpest knife in the drawer, sticking the old arm in there like that. Gonna be calling that fella “Lefty” someday, you betcha.

Yet another weapon engineering advance brought to you by: Unser geist of Germany.

Wow, hope there’s a pressure release valve in there somewhere. that thing might go all splody. Fraking cool nonetheless.

Maby Tippman will make a paintball marker that runs off dry ice. That would be pretty cool for the next scenario game.

I made something similar several years ago to shoot potatoes: http://nullprogram.com/blog/2009/07/20/dry-ice-potato-gun

Dont think the pressure would be high or as constant enough to control dnd_designer. Still its a maybe.
