🏊‍♀️ Have you ever looked at your hands after a long swim and shouted, "I have raisin fingers!"? Why does that happen? Is Ziggy right... are we secretly sponges? (Bleep-bloop! Hypothesis!) Or, as Dr. Owl explains, is it a secret message from your brain to give you... SUPER-GRIP? Join Emma, Ziggy, and Dr. Owl at the pool to find out why your fingers have their own built-in "rain treads." We'll do a mini-experiment, answer our very first listener question, and learn the amazing science behind getting wrinkly!
