Synopsis: Medfield's lovable but hopelessly absent-minded professor -- Ned Brainard (Fred MacMurray) -- bounces back in this classic Disney film with hilarious new mishaps when he experiments with the amazing by-products of his startling anti-gravity substance, "flubber." Windows shatter, football players fly, and thunderstorms materialize indoors as Professor Brainard fights to keep Medfield College from falling into the hands of ruthless land developer Alonzo Hawk (Keenan Wynn).
