Today Kit and Pup are exploring the opposites Open and Close. They start by trying to pack a suitcase. Pup manages to close it neatly, but then Kit overloads it with clothes and the suitcase keeps popping open. Kit and Pup then try to find as many things being opened and closed as they can. In the live-action investigation Kit and Pup help the little investigators find matching pictures of open and closed objects. And in the stop-motion moment a paper butterfly opens and closes its wings.
