the ball bounced higher on its second bounce than on its first. For a more successful demonstration, he makes his Model T fly by bombarding Flubber with radioactive particles. He puts Flubber on the soles of basketball players' shoes in a crucial game, giving them tremendous jumping ability; he also uses the substance on his own shoe soles to augment his skills during a school dance. Scheming businessman Alonzo P. Hawk becomes aware of Professor Brainard's flying car and, at Biff's suggestion, switches it for a fake. Professor Brainard's debut turns into a mockery when he finds himself with a fake Model T powered by squirrels and pigeons. Realizing it was Hawk's doing, Professor Brainard plays on Hawk's greed by pointing out that, in the 1960s, only 8% of the world's population uses cars, but nearly everyone wears shoes. Professor Brainard gives Hawk a pair of Flubber shoes; soon, Hawk cannot stop bouncing, and is blackmailed into revealing where he hid the Professor's car. A bouncing Hawk soon attracts everyone's attention, even a news crew, who interviews a physicist who sees Hawk keeps bouncing higher with each jump and remarks "by 7 tonight, he's going to be in serious trouble!". The police escort the Medfield football team to tackle Hawk on his way down, stopping his bounces. Hawk and Biff then chase after the Professor, who by now has recovered his car from Hawk's warehouse. Hawk crashes into the same squad car Shelby did, and gets arrested for illegal firearms possession. Professor Brainard convinces Betsy to accompany him to Washington, D.C. Never seeing a flying car before, the military considers it an attack and is ready to open fire until one junior officer recommends against it, as Professor Brainard is atop the United States Capitol building. Now able to convince the government of the merits of Flubber, Professor Brainard finally marries Betsy. Cast Production notes The aforementioned Prof. Alyea (1903–1996), professor of chemistry at Princeton University, earned the nickname "Dr. Boom" from Russian observers of his demonstrations at the International Science Pavilion of the Brussels World's Fair in the 1950s, which had Walt Disney in attendance. Disney told Alyea that he had given him an idea for a movie, and invited Alyea to California to give a demonstration for actor Fred MacMurray, who later mimicked Alyea's mannerisms for the film. MacMurray would later state that he had never understood chemistry
