In this episode, we are trying something different. Instead of following a specific topic, we answer questions that listeners have sent us. We learn about the amazing complexity of our bodies and how they move, electricity and how lightbulbs are made, why cheetahs have lines on their faces and why dinosaurs were so big. We look at why spiders have 8 legs and if flies have bones in theirs. We also touched on coffee, our favourite topic, and whether coffee beans are actually beans. Finally we look at sunscreen and how it helps to protect us from the sun.
