Mark Rober, a former engineer who worked at the Jet Propulsion Laboratory (JPL) of the US Space Agency (NASA), has successfully built a 2.1 m long toy water gun that can shoot out. water jet with a speed of 437 km / h, enough to smash a watermelon and break a window, Red Orbit reported on July 12.
Guinness World Records certified this as the largest water gun in the world. Although the gun is huge in size, its mechanism of action is similar to the smaller versions of water guns sold in toy stores. Rober compresses air, in this case nitrogen gas, into a tank of water, then pulls the trigger to fire.
Rober provides parts lists and installation instructions for those who want to build the gun. The air pressure used for the gun is very strong and dangerous. Therefore, manufacturers need to proceed carefully, especially when working at home.
This is not the first time that Robert has created giant guns. Last summer, he built the world's largest Nerf gun.
