When the creators of the popular science show with millions of YouTube subscribers comes the

Minute Earth podcast. 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

Our team of scientists digs into the research and breaks it down into a short, entertaining

explanation, jam-packed with science facts and terrible puns.
