What do you do when something cracks? Andrew & Polly talk to Everett (from South Africa), Henry & Saul, Jackson & Beanie and Ainsley about things that break. Elizabeth Cochran from the US Geological Survey, aka Doctor Earthquakes, talks about seismology and Everett (from Los Angeles) shares a special story about what happened when he cracked the bones in his arm. Some things crack by design - like eggs! But it can be really surprising for kids when something breaks, especially if that thing can't be repaired.  In this episode, we think about what to do about the unpredictable - breaking something by accident and preparing for earthquakes.
