Finally home! Sigrid talks about her trip home and how it feels to be back after a month away.

The travel kids visit a town almost completely covered by volcanic rock some twenty years before. There’s not a great deal left of it for them to see! They walk out onto the glassy and slippery surface of the lava flow, where volcano expert Ken takes a sample of some liquid rock to measure the temperature. It’s super hot, and Julian makes the excellent decision to keep his hands well clear!
