The 6-foot-long toy gun, constructed by Mark Rober, was named the “World’s largest Nerf gun” by the Guinness Book of World Records.
A mechanical engineer in California, USA constructed a massive Nerf gun in the hope of one-upping his coworkers.
“It’s really cool to make it into the Guinness World Records 2017 Blockbusters! book,” he said. “I never thought I would get one but it’s always been a secret bucket list kind of thing. I now have the official certificate hanging in my office.”
He said the biggest challenge was harnessing the pressure that allows the gun to fire massive foam bullets made of a pool noodle and a toilet plunger at speeds of up to 40 miles per hour.
Rober showcases various other inventions and science experiments on his personal YouTube channel.
He first came up with the idea to construct the gigantic toy weapon to escalate an ongoing office Nerf war.
