A YouTuber in Russia has set a new world record for the first working, retractable lightsaber. The Star Wars-inspired technology uses white-hot elemental plasma, can run for up to 30 seconds at a time, and can even cut straight through steel. And even better: it’s mostly crafted from old, discarded parts.
In January, Guinness World Records recognized Alex Burkan, the mind behind the DIY lightsaber, for his invention. He frequently posts zany, but technically impressive projects on his YouTube channel Alex Lab, which has over 875,000 subscribers as of press time. There, you can find his epic builds, including hydrogen generators, Iron Man suits, and of course, his lightsaber, which produces an impressive three-foot-long plasma “blade” that can reach temperatures over 5,072 degrees Fahrenheit, according to a press release.
But since he mentioned Hacksmith Industries, I thought I’d show you that one as well:
Please, folks, you may wish to think hard and long before trying this without any training.
