Hoping to stop people picking on him during Nerf battles at work, former NASA engineer Mark Rober built the world’s Largest Nerf gun, assisted by Ryan and David, hosts of the science YouTube channel Eclectical Engineering.
“Everyone in the office has Nerf guns and they shoot each other with them,” Mark said. “I started thinking about how to one up my fellow engineers. I had a few different ideas, but eventually decided to go big or go home.”
His supersized blaster measures a whopping 6 ft (1.82 m) long.
The air-powered projectiles – which at 24 in (61 cm) are almost nine times the length of standard Nerf bullets – leave the barrel at roughly 40 mph (64 km/h)!
They were made from pool noodles and toilet plungers.
Mark, who collected several Guinness World Records books when he was younger, said: “Friends and family are no longer impressed when I make a YouTube video that gets millions of views, but I got quite a few high fives when I told them about earning a GWR title.”
Mark is 37 years old and lives in Sunnyvale, California, USA.
He has placed a target on more Guinness World Records titles with plans to attempt more records, but is keeping them secret for now.
The largest Nerf gun appears in the brand new Guinness World Records 2017 Blockbusters! book alongside loads of jaw-dropping records from the world of movies, toys, social media and beyond.
The book is out now in the US but will be coming to the UK and Australia in March.
