From one glance at his YouTube page, it’s clear that user styropyro is a laser aficionado. He’s built light sabers, upgraded laser pointers, and just generally screwed around with burning stuff—and this laser shotgun may very well be our young inventor’s magnum opus. This guy is made of eight parallel 5W laser beams and incinerates everything from ping-pong balls to firewood, all from the comfort of stryopyro’s garage. As always, we must insist that you please don’t try this at home. But feel free to add it to your Pinterest board.
D.I.Y. just got way more compelling.
