yes, starwars does funny things to your mind. ok, guys, i made a lightsaber. i have a car battery in a backpack, with two wires connected to it. the wires come out of the backpack, into the hilt, and connects to some coils. the hilt is about 30cm long. when i want to turn the saber on, i push on the bottom of the saber, and it pushes the coils up which in turn touches the metal blade on the inside of the hilt. The blade is designed with holes in the side so that they extend, but dont fall off. the electricity charges the extending blade, which is hollow, but made of iron. the blade is charged with electricity, and is glowing BLUE, and is really hot so i can cut stuff with it so its really not that hard. only problem is u need that backpack with the car battery. ill post some screenies soon. another problem is that u gotta wait for the saber to heat up before u can cut stuff.... although u CAN electrocute things with it.
