Allen Pan American engineer constructed a functioning lightsaber. Instead of a laser, the burning fuel acts like a blade, reports.

Although the device looks like a lightsaber, in practice, it is rather a flamethrower. In the handle sword there is a tank with fuel (a mixture of acetone and methanol) and author uses butane as the propellant. The cylinder with the fuel is separated from the nozzle with a special screen, to ignite the fuel Pan uses nichrome thread. On the handle there is a fuel supply button, which is also responsible for the sound effects.

The challenge of creating a device that looks and functions like a real lightsaber has long been the subject of practical and thought experiments. The result isn't even a fraction as powerful as a true lightsaber, but it looks like one and can set things on fire at least.
