Best Homemade Arrow Shooter Ever? Kills 2 Zombies With One Shot. ─ JoergSprave

The best commercially available crossbows have about 200 Joule shot energy and 3 N s momentum. That is quite impressive and actually can be used for hunting big game at shot distances up to 70 meters.

But now, a home made "post apocalyptic" airbow wipes all of those expensive products away. Made from plumbing parts and wood from the scrap heap, this arrow powered weapon fires a heavy, thick home made arrow at 511 Joule (377 ft-lb) of energy, with about four times the momentum of a 200 Joule crossbow.

It is accurate enough to achieve a perfect "Robin Hood" shot from 14 meters distance, and can be charged by a manual pump, a scuba/paintball bottle or a suitable compressor.

The power is just amazing. Even a triple layer "Stronghold" archery mat that can easily stop the most powerful compound crossbow arrows failed to catch the heavy aluminum arrow fired from this contraption... but clearly the most impressive test is the "double Zombie" head shot. Two coconuts, molded into two blocks of ballistic gelatin, were penetrated all the way with major force.

This needs to be converted into a commercially manufactured airgun with a quick reload, large air container and cool industrial design! Specifically since German law defines this as a "toy" and it can be bought/made without any kind of license.

A "The Slingshot Channel" production!
