Brilliant but befuddled Professor Phillip Brainard (Robin Williams) is on the brink of inventing a revolutionary energy source and missing his wedding to fiancee Dr. Sara Jean Reynolds (Marcia Gay Harden) -- president of financially challenged Medfield College -- for the third time! When Phillip experiments with his own big bang theory, a miraculous elastic good -- Flubber -- emerges, leaving him ecstatic, but unmarried! Phillip and his flying cyber sidekick, Weebo, soon discover that Flubber, applied to anything, enables it to bounce super high and fast. However, many questions remain. Is Flubber good enough to win Sara back, save Medfield from its financial problems, and slip through the hands of the evil financier who is bankrolling the college? FLUBBER slips, slides, giggles, glides, flips, and flies -- the stuff of surefire family entertainment.
