A laser fitted into a watch that can actually do some damage; sounds like the stuff right out of spy movies, right? Well thanks to technology, such a device now exists. Put together by Patrick Priebe, this is a watch that can actually fire out a laser that is strong enough to burst balloons, and presumably burn some skin in the process if you’re not careful. The watch features a 1,500-milliwatt blue laser that unfortunately is a very huge battery drain.
