Devin Coldewey NBC News AnselmoFanZero / YouTube The laser device lit up but stationary. Many fans of sci-fi books, movies and video games have encountered the concept of a "Gatling laser gun" or something like it, with rotating barrels and exotic projectiles. Now a laser-loving gadgeteer has made a real-life one — though its destructive capabilities are limited to balloons for now. Patrick Priebe, who runs Laser-Gadgets.com and goes by the name AnselmoFanZero on YouTube, showed off his creation in a video uploaded earlier this week. Six "Arctic" blue lasers from Wicked Lasers and an extra green one for aiming are mounted on a futuristic-looking case. When turned on, it creates six extremely bright blue beams that are rotated rapidly by an internal mechanism. It's all very cool-looking, but it doesn't make the lasers more powerful, and it's not really a Gatling gun, either. .
