We heard that Gavin Tolometti 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.

Look for more info on Gavin's work on his blog at
