  • Could you make a real-life lightsaber?
    Dec 29 2022

    A long time ago, in a galaxy far far away… we wondered, could you ever build a real lightsaber like the ones in Star Wars? A lightsaber is a glowing sword that can cut through metal – and pretty much anything else you can think of. It’s the favorite tool of heroes like Luke Skywalker and Ahsoka Tano, as well as villains like Darth Vader. That’s just in the movies, but could we make them real? We asked mechanical engineering professor Sayan Biswas to help us find the answer.
