4000° Real Life Retractable Plasma LIGHTSABER Test [Video]

Youtuber The Hacksmith recently built a real life retractable plasma lightsaber that can actually cut through metal, but he only released the demo video of it in action today. For those who are curious, the beam is made from a mix between liquid propane gas and oxygen, “mixed in a really fancy laminar flow gas nozzle.” Check it out below!
