第 1 季，第 105 集: Do you remember the first time you ever rode on an elevator? Didn’t it seem like magic, getting in the elevator at one spot and getting off in a different spot? SuperHands is here to teach your little ones that even though it’s not magic pulling you up and down in an elevator, it’s still something pretty amazing and it’s called science! Come along with SuperHands in this brand new episode of SuperHands Science from PlayKids as we learn how simple machines called pulleys are responsible for moving elevators up and down.
