One thing you can say about Star Wars is that it brought us the coolest weapon ever in the laser sword they call a lightsaber. Both high-tech and medieval, it's perfect for hand to hand combat and for slicing your enemy in two. And they come in cool colors!

This chart made me want to see a turquoise lightsaber, but I was really curious about a black lightsaber. Read about the research that went into this chart at FiveThirtyEight. The links there are liable to send you down a Star Wars rabbit hole. -via Digg
