Note: SOUND ON.
This is a clip of Instagram user vilalaseroficial using a powerful burning laser to clean the oxidation and tarnish off an old pendant crucifix. I saw Jesus move! The sounds it makes are equally miraculous. Per a commenter, “that’s the sound of the laser vaporizing a thin layer of material. The changing pitch is due to how quickly the laser is oscillating across the surface since it’s just a single beam sweeping back and forth really quickly.” Damn, I really want one of these lasers. You think I could use it for hair removal too?
Keep going for the video, as well as a watch and coin cleaning (the coin is particularly wild).
