Bill Nye has returned to perform experiments with glee as evident in the first trailer for his new Netflix series, Bill Nye Saves The World. The 13-episode series finds Nye investigating topics ranging from sex to alternative medicine. Or, as Nye put it during the panel in New York this morning: “We have climate change and video games.” Special guests are promised to pop up, including Rachel Bloom and Tim Gunn. Nye has also enlisted correspondents like model/entrepreneur Karlie Kloss, as well as STEM speaker and Xploration Outer Space host Emily Calandrelli. Nye was keen to point out that it premieres on the eve of Earth Day, April 21.
