He first built you Thor’s hammer that only he could lift, now he brings you a real-life lightsaber, blue flame and all, (essentially a is flamethrower that runs on alcohol).
Pan explains in the video how he made the lightsaber. He used methanol, acetone and butane to create the blue flame, and also added sound effects so that his lightsaber makes that same buzzing sound that the ones if the movies do. May the Force be with you!
