Error in Lightsabers.
There is something I've always found wrong about the lightsabers in Star Wars. It began when I watched Episode II when Anakan got his arm chopped off, I noticed there was no blood, but it was because the lightsabers are so hot that it burns the wound. But if that's true, since the lightsabers are so hot, that the heat would travel through the metal handle and burn the Jedi's hand- 😛 Metal conducts heat!
