At the museum, George discovers something he has never seen before-a vending machine and becomes curious as to how one works, thinking there is a farmer and an apple tree inside an apple machine. But then someone shows him what is really inside, a series of simple machines. The Man is asked by Professor Wiseman to host a party for two expedition groups at his apartment and leaves George in charge of dessert. So George decides to build his own vending machine to make it.
