This is a video of the folks at Youtube channel The Hackensmith testing the world’s first retractable plasma lightsaber, the construction of which they featured in a build video last week (included below). The lightsaber burns at around 4,000-degrees Fahrenheit (2,200-Celsius), is powered by a mix of liquid propane and oxygen, and you can absolutely forget about me putting my hand in front of it for anything less than ten dollars.

Keep going for the testing video, followed by the build.
