You'll want to pay attention to the don't-try-this-at-home aspect of this video because you really don't want to try this at home unless you feel like burning the place down. That said, wanna see what a real-life lightsaber might look like if one were created using today's technology? Sure we've got all kinds of lightsaber replicas on sale at your local toy stores and in the homes of thousands of Star Wars fans worldwide, but those interested in the real deal need to know their way around some pretty dangerous lasers.
Here's a video from the DIY Laser Guy (who should probably call himself the Don't Do It Yourself Laser Guy) in which he takes the most powerful laser he's ever worked with and utilizes it to build a lightsaber. While this lightsaber can't exactly slice through everything, it can light things on fire pretty easily and we definitely wouldn't want it touching any part of our bodies. Watch below as our resident laser guru uses his makeshift lightsaber to burn various items around his house.
From the YouTube description: "This laser uses the new 9mm 450nm laser diode and runs on two 18650 Li Ion batteries. The housing is a custom machined 'Sirius' host. I usually try to refrain from using the term "lightsaber" when referring to my lasers but there really isn't much else out there to describe this laser."
Okay, who wants one?
