Drake Anthony knows lasers; he first went viral a few years ago by building a “lightsaber” that could ignite wood. Well, he’s at it again, this time with a short-range laser shotgun.
The design is fairly simple; there’s a 40-watt laser array mounted in the middle of the gun, firing beams into a lens at the end of the barrel. The lens focuses the light on anything you want, and that object, in turn, tends to light on fire or explode. Balloons, wood, ping-pong balls, black powder… this is apparently pretty good at igniting small objects you have in your garage.
Before you ask, yes, this is legal; there are no laws on the books regarding the owning and operation of laser arrays, even if they explode things. Fortunately, Drake seems like a calm guy, so we probably don’t have to worry about him taking over a small Eastern European country with superscience. Probably.
