Joe Hanson is a scientist who hosts PBS Digital Studio’s It’s Okay to Be Smart and Hot Mess, a new YouTube show about climate change. He’s been a longtime friend of Tumble’s, so it was a no-brainer to ask him to help answer listener questions!

Joe tells us why penguins can’t fly, how animals breathe underwater, what’s beyond the universe, and why our teeth get wobbly and fall out. Plus, find out what we think Tumble: Aquatic Edition would sound like!

Watch some of our favorite of Joe’s videos on our website: sciencepodcastforkids.com/blog.

Don’t forget, a great way to support Tumble is to pledge on Patreon. You can also tell five friends about the show! Either way, we’ll love you.
