Every episode of the show dives deep into a science question you might not even know you had, but once you hear the answer, you'll want to share it with everyone you know. Why do rivers curve? Why did the T-Rex have such tiny arms? And why do so many more kids need glasses now

than they used to? Spoiler alert, it isn't screen time. Our team of scientists digs into the

research and breaks it down into a short, entertaining explanation, jam-packed with science facts
