Kavi's Spinning Earth
Kavi holds a torch 🔦 still and slowly spins a ball 🌍. "The torch is the Sun, and the ball is Earth! See — the side facing the torch is bright, that is day. The side facing away is dark, that is night." Kavi gives the ball one slow turn. "When Earth spins all the way round, we get one whole day and night. Let's use this model to explain the day and night we live in!"
