Butternut Street tells the story of an eccentric but delightfully lighthearted inventor who moves into a house next to one occupied by two young children, their parents and their kitties. The inventor turns to the children with a twinkle in his eye for their ideas in solving problems with his flummox machine. With their parents' permission, they respond with creativity and imagination. They utilize ordinary household items, like a sheet of plastic, a laundry basket, a mirror and a candle to enable the machine to fly. The whole neighborhood celebrates the accomplishment.
