Now look, we don't want to get you too excited but someone has built a lightsaber from Star Wars, and we don't just mean a giant laser pen. This thing is a flaming sword of awesome that'll cut down balloon shaped Stormtroopers and casually light cigarettes.
The result is a fiery blue stream which looks and behaves uncannily like a lightsaber.
One of the problems with laser pen version is that not only are they enormously dangerous for people up in the sky but also they have no end.
The classic lightsaber somehow ends, and this is the closest thing we've ever seen to accomplishing that.
Sadly it looks both complex and dangerous to build so we're going to say that you absolutely should not be trying to make your own.
