Flubber - Magical substance invented by Prof. Brainard in "The Absent-Minded Professor," and later the title of a sequel, i.e. "Son of Flubber." Walt usually resisted making sequels to his successful movies, always protesting that he liked doing new things without repeating what he had done in the past. In the case of "Son of Flubber," he relented, and the movie was a smash hit -- thanks to special effects like the one in this photograph.
