The popular influencer from Canada, James Hobson, known as “the Hacksmith“, has over 10 million subscribers on YouTube. He is also well known for turning science fiction into reality.
The lightsaber, inspired by Star Wars, runs on propane gas burning at around 2,000°C that creates a retractable plasma beam.
James used liquid petroleum gas – commonly found in barbecues. The liquid fuel is mixed with oxygen and turned into a superheated beam of plasma via laminar flow, a physical phenomenon which allow liquids to flow smoothly.
The beam of gas can also change colour with the addition of various chemicals. To show how devastatingly effective the lightsaber is, the team used it to cut through metal in the video below.
