Mark Rober, a former engineer who worked at the Jet Propulsion Laboratory (JPL) of the US Aeronautics and Space Administration (NASA), successfully built a toy water spray gun with a length of 2.1 m that can be fired. water jet at 437 km / h, enough to smash a watermelon and break the glass, Red Orbit reported on July 12.

Guinness world record organization certified this is the world's largest water gun. Although the gun is gigantic, its mechanism of operation is similar to the smaller version of water guns sold in toy stores. Rober compressed the air, in this case nitrogen gas, entered a water tank, then pulled the trigger to fire.

Rober provides a list of parts and installation instructions for those who want to build a gun. The gas pressure used for the gun is very strong and dangerous. Therefore, manufacturers need to be careful, especially when working at home.

This is not the first time Rober has made huge guns. Last summer, he built a gun that fired the world's largest nerf gun.
