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.

So far, only adults have been to space. But there are plenty of kids who’d love to travel to space, so what gives? Why can’t kids walk on the moon? Or visit the International Space Station? We asked NASA engineer Varoujan Gorjian to help us find the answer.

Clay is neat stuff. You can knead it, shape it, carve it, sculpt it, and make all kinds of beautiful creations. It goes from soft and squishy to hard and breakable when it’s baked in a kiln. But clay is…dirt, right? It comes from the ground! So how do you get it out of the ground and into the blocks that you find at an art supply store? We asked ceramic artist and educator Lauren Sandler to guide us through the process.
