Mind To Change/Curious Minds
Season 3, Episode 17 of 20
Sally is convinced that a tall thin glass of juice holds more than a short wide glass so Cat takes them to Point O'View where they learn that getting evidence can cause them to change their mind. Nick and Sally wonder if they can walk on a cloud, and the Cat takes them to Mount Knowmore. As they climb, they discover that materials have different properties that allow them to be solid or fluid. And when they get to the top, they have gathered enough evidence through experience of walking through the clouds to answer the original question.
