We heard that Gavin works with lava, and we thought you should hear about that too. He's smashed solid lava with a hammer. Has melted it in a furnace. Sliced it into hair-thin discs. Because somewhere in there is the key to understanding our moon and many extraterrestrial planets. Join Susan and Navaneeth as they discover how to research on the rocks.
