James Hobson goes by the name The Hacksmith on YouTube and his devoted followers have come to expect great things from him.

And he did not disappoint when he tried and successfully built the world’s first real-life lightsaber, which is plasma-based and yes, it’s retractable.

It burns at 4,000 degrees and is capable of cutting through steel. Hobson also figured out how to make the lightsaber burn in different colors.
