 In Prague, a professorial puppet, with metal pincers for hands and an open book for a hat, takes a boy as a pupil. First, the professor empties fluff and toys from the child s head, leaving him without the top of his head for most of the film. The professor then teaches the lad about illusions and perspectives, the pursuit of an object through exploring a bank of drawers, divining an object, and the migration of forms. The child then brings out a box with a tarantula in it: the professor puts his "hands" into the box and describes what he feels. The boy receives a final lesson about animation and film making; then the professor gives him a brain and his own open-book hat.
