About this episode
Our big, beautiful sky stretches all the way from the ground beneath our feet to about sixty miles above the Earth. It’s made up of countless air molecules, pinging around like tiny, invisible pinballs. And even though we can’t feel the weight of each individual air molecule, all together they weigh a lot! But how much does the sky actually weigh? (spoiler alert: it involves lots and lots of farting cats…) Molly and co-host Felix learn more by talking with a band of singing walruses and a pretty wacky weatherwoman. And don’t miss this week’s extra mysterious Mystery Sound! This episode was sponsored by: Indeed ( Indeed.com/BRAINS - Terms and conditions apply.
