This is a video demonstration of a laser-based rust removal gun. Lasers: is there anything they can't do? I'm not really sure what's going on, but it looks like it works. It also looks worlds easier than using a grinder. Still, the question remains how good it is at hair removal. I'm guessing really good. Now do my eyebrows.
Keep going for the video.
Thanks to pyrat hero!, who uses laser blasters to commandeer larger ships and steal their treasure.
