XTech at the Exploratorium empowers high school students through the practical use of Science, Technology, Engineering, Art, and Mathematics. Students develop skills - designing and building, creating media, and facilitating community education events - that will lead them into college and beyond. In this show, we will be investigating lasers. Did you know that that LASER was an acronym? It stands for Light Amplification Stimulated by the Emission of Radiation. Join us in learning how a laser works, as well as a real world application for lasers, and finally, how they can create stunning light patterns.
