Flubber Magical substance invented by Professor Ned Brainard in The Absent-Minded Professor. Disney gave away its formula for making Flubber in the film’s publicity: “To one pound of salt water taffy add one heaping tablespoon polyurethane foam, one cake crumbled yeast. Mix until smooth, allow to rise. Then pour into saucepan over one cup cracked rice mixed with one cup of water. Add topping of molasses. Boil until it lifts lid and says ‘Qurlp.’” At the time of the film’s release in 1961, Hassenfeld Brothers (Hasbro) made a pliable plastic-like material that they merchandised as “Flubber.” It sold for $1 and was advertised as “Every bubble a bounce.”
