As you see Priebe use the watch-we-all-wish-we-had in the video below, you'll notice a blue glow on his hand. I asked him if he was worried about torching his own skin with the laser. "The blue shine on my hand is really just that," he said. "If the beam hits your hand, it will get warm very quickly, and I would probably stop pushing the button. It's in fact capable of burning your skin though. Not exactly a toy."
