Russian YouTuber's retractable lightsaber earns Guinness World Record

Jan. 24 (UPI) -- A Russian YouTuber has been recognized by Guinness World Records as the inventor of the world's first retractable lightsaber.

Alex Burkan, who runs the Alex Lab channel on YouTube, unveiled his Star Wars-inspired invention

which produces a plasma blade that measures more than 3 feet in length and burns at a temperature of 5,072 degrees -- hot enough to cut through steel.

 An electrolyzer is a device that can generate a huge amount of hydrogen and oxygen and compress the gas to any pressure without a mechanical compressor," Burkan told Guinness World Records.

He said it took hundreds of experiments to get his apparatus to match the size and shape of a lightsaber hilt.

This is a first prototype so it has lots of limitations. It works for only 30 seconds on full power, the hydrogen torch is not as stable as it could be and you can easily see it when it moves

Sometimes the lightsaber just blows up in your hand because of hydrogen flashback," he said.

Fellow YouTuber Hacksmith Industries, aka James Hobson, previously earned a Guinness World Record for creating the world's first retractable proto-lightsaber.
