Making a Light Saber

Materials requires:-
2 Any color LED's you want
Paper
A box with a lid with a hole in its middle
battery
momentary switch

Take the battery and attach a switch to it and then connect it to the LED and then connect the other end of the battery to the LED as well.

Take a piece of paper and roll it into a tube and cut a small rectangle for the switch and then put the lighting system in with the LED in the middle and the switch in the rectangle hole.
Turn the switch on and voila your own cheap lightsaber.
