Overkill is an understatement.

Mark Rober and Bob Clagett's 7-foot-long Super Soaker water gun is a beast of a thing that 's powerful enough to slice through watermelons and break glass and you definitely won't find it in a shop any time soon.

Powered by pressurised nitrogen, this water pistol is more powerful than a fire hose and shoots at up to 243mph. Which basically makes it a weapon.
