The recent release of Star Wars: The Force Awakens has fueled some of its fans to take their adoration to whole new levels. There have been some videos trending on YouTube on homemade laser lightsabers. Styropyro is one of them. It has built a lightsaber using a heavily upgraded 7W blue laser which is several times more powerful than what’s needed to blind someone. It is strong enough that it can burn through wire and other household objects though the beam isn’t contained like the “real” thing.
You need not worry if 7W does not sound impressive. Styropyro is teasing progress on a laser bazooka that would combine multiple 40W lasers. It won’t be nearly as portable as the lightsaber, but it could put on an even bigger show.
Clearly the Star Wars series is blowing everyone’s mind now. The movie has such an impact on the viewers that it perhaps encourages them to go for experiments that are risky and need precautions.
