Former NASA engineer builds the world's largest Super Soaker

Do you remember the 'Super Soaker' from your childhood? I had one, but I never managed to cut a watermelon in half with it. The ordinary toy just won't do that, but when your dad is a former NASA engineer and builds one for you, I'm pretty sure nobody wants to face-off against your water gun in a backyard battle.

At seven feet long, Former NASA engineer Mark Rober officially holds the Guinness World Record. His super-sized Super soaker fires water at 272 miles per hour (438 KM/h), which is enough pressure to shatter windows or to slice a watermelon.

Enjoy the video:

"I made the world's largest Super Soaker as a follow up to my World's Largest Nerf Gun. It shoots at 2,400 psi and 243 mph. I destroy a bunch of stuff in slow motion and talk to the inventor of the Super Soaker Lonnie Johnson." ~ Mark Rober

The world’s largest Nerf gun

It's not the first time Mark Rober made a little overpowered children’s gun. A year ago he made the world's largest Nerf gun which can shoot darts at 40 MPH (64.37 KM/h).

Totally hilarious!
