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!

The kids now look for "The London Eye," with the hint that it is something that people can ride on. Once they find it, they go to take a look at the Tower Bridge.
