Former NASA Engineer Built the World's Largest T-Shirt Cannon

Then unleashed it on unsuspecting football fans.

In answer to an odd request from his friend Jimmy Kimmel, former NASA engineer and YouTuber Mark Rober has tackled the hefty task of building the world's largest t-shirt cannon. To give you a little bit of background, Kimmel said that his dream was to have the world's most powerful t-shirt cannon for Jimmy Kimmel LA Bowl.

To make Kimmel's dream a reality, Rober collaborated on the design with Anthony Hartman, a 12-year-old fan and an aspiring mechanical engineer. The duo discussed everything over video calls, and Hartman built a miniature version first to ensure everything would work in the final design. The tests were done in SoFi Stadium, where the game would be played. After confirming that the cannon can shoot, and getting approval from lawyers about safety concerns, it was time to unleash the cannon on unsuspecting football fans. During halftime, Rober, Hartman and Kimmel fired the cannon, and if you want to see the demonstration in action, make sure you watch the video embedded above, and as always, enjoy.
