Penelope K, by the way - Gravity

Penelope K runs the Information Station, a place which contains all the answers to any question a child might have. To help her find the answers, Penelope is joined by her sock puppet, Squirm; Hank and Frank, two wise cracking fish; Trewey, the shadow rabbit, and music is provided by the Rubber Band. Penelope K investigates why nothing flies off the Earth into space. After making some spin art, listening to a story about a baby rabbit who forgot to hold onto a round about, and experimenting with a magnet, the Rubber Band tells her about an invisible force called gravity which keeps everything firmly on the ground. Astonishing!
