A cool gadget for Star Wars fans

With the release of the new Star Wars movie "The Force Awakens" there are some self professed geeks who have designed their own light sabers. "Styropro", a Youtube guy who dives heavily into laser technology has devised a 7W 'lightsaber".
Now 7 watts may not sound powerful, but it can burn through wire and other household objects. He's also working on making a "laser bazooka" that will combine multiple 40w lasers for even a bigger punch.
