Bill Nye deals with the crust of the Earth in this episode of his award winning series. While he uses many devices to connect with kids, including humor and general silliness, he never condescends. In Bill Nye the Science Guy: Earth's Crust, the Science Guy takes a tour into the layers of the Earth, all the way to the "gooey center." A hint of the core's heat comes when volcanoes erupt and hot lava flows.
