Wheeeee! How do slides work? What makes something slippery? And what happens when one person wants to go down a slide and another person wants to go up? Andrew & Polly think about the physics of playgrounds, sledding, trombones, and outer space. Our friends Oscar, Alexis, Calvin, Monroe, Tenney, Ainsley, and aerospace engineer Frankie help us make friends with gravity and friction. Plus we turn a playground structure into a percussion instrument. You can hear the full version of the song featured at the end of the episode “The Scientific Method” (feat. Mista Cookie Jar) on Andrew & Polly’s GRAMMY-nominated album “Ahhhhh!” wherever your get your music. Thanks to Shopify for supporting Ear Snacks!
