If you’re looking to relive the childhood innocence of pelting your friends with foam darts, but to a much more dangerous level, look no further. The world’s largest Nerf blaster has been engineered by science Youtuber and former NASA engineer Mark Rober.
Along with scaled darts made from pool noodles and plunger heads, he uses his creation to do everything from shattering glass to skeet shooting. He even takes down a few children, including his nephews and niece, along the way.
He powers it with a 3,000 PSI paintball tank that allows him to fire his darts at 40 miles per hour. For more on how it’s made and what it can be used for, watch the Nerf-tastic video above.
