Summary: Professor Walter Mayhew has always been weird, but an explosion in his backyard laboratory seems to have sent him over the edge. Then he disappears -- in bizarre circumstances. Three of his young proteges, Max, Jian Xin and Cleo, start receiving cryptic messages, which look like plans for a nuclear device -- one which could solve all of humankind's energy problems. The children decide to make the device for the upcoming ExpoFest science fair -- but if it works, the technology will be worth a fortune. And certain people aren't about to let three kids get the credit.
