The principle of [NightHawkInLight]’s design is simple – an electric leaf blower provides the power, and a big vat o’ poofs provides the ammo. Getting the two together and providing a barrel is a matter of some simple plumbing with 1″ PVC pipe and fittings. But wait – lest you think this hack, like the ammo, is just a delicious bit of fluff, there’s something to be learned about fluid dynamics here.

But by adding a small restriction to the incoming air flow, the Venturi effect actually sucks ammo into the chamber and down the barrel, to the delight of hungry wildlife for yards around. Science!

There’s plenty of room for improvement to the design – something along the lines of this gas-powered, tube-fed snowball gun would be keen. As it stands, the cheesy-poof gun seems like good, unclean fun.
