omg paul you swore............................and i hope your joking because that doesnt actually work and the ones at like walmart and stuff are G-A-Y
It could acctually be possible to make somthing similar to a light saber. I dunno if they've figured out yet how to make a laser a certain length or not though. They probably have. If so they could make a one. Although you wouldn't be able to hit them together or anything you could still cut people in half with it
or heres a funy thought they could have like a heater in the handle on say a sword so it heats up the metal blade on the sword there fore allowing you to hit them together and make sparks and cut through people and of course the downside is you cant ajust the length, and you need something to glow and make it look like its round
