Slingshot master Joerg Sprave is known chiefly for his rubber band-based weapons, but that’s by no means his only area of expertise. After turning a single Coke bottle into an air-powered arrow cannon, Sprave decided to take his dangerous device to the next level of absurdity. Meet the Coke Bottle Gatling Gun.

The mechanics here are simple. Each Coke bottle serves as a reservoir for air, pressurized by a bike pump. The airflow out is regulated by a valve, and when the blast is released it races out the barrel on which the arrow sits. In short, FWOOM.
