  • A college professor invents an anti-gravity substance which a corrupt businessman wants for himself.

  • A bumbling professor accidently invents flying rubber, or "Flubber", an incredible material that gains energy every time it strikes a hard surface. It allows for the invention of shoes that can allow jumps of amazing heights and enables a modified Model-T to fly. Unfortunately, no one is interested in the material except for Alonzo Hawk, a corrupt businessman who wants to steal the material for himself.

  • Ned Brainard is a Science teacher at a College who's obsessed with his experiments that he forgets other things like his weddings to his girlfriend, Betsy. He misses the latest one when his latest experiment blows up. And he discovers a substance that defies gravity, which he says is flying rubber which he calls flubber. He then places it in a Model T which enables it to fly. Alonzo Hawk, a banker who's upset with Brainard for failing his son in his class making him ineligible to play in a big basketball game. When the team is losing, he places flubber in sneakers which allows the players to make high leaps. Eventually Hawk sees Brainard flying in his Model T, he then asks him for the secret so he can make a fortune from it. But Brainard decides to give it to the government instead. So Hawk decides to steal the car. So Brainard has to try to get it back.


The synopsis below may give away important plot points.


  • Professor Brainard (Fred MacMurray) is an absent-minded professor of physical chemistry at Medfield College who invents a green substance that gains energy when it strikes a hard surface. This discovery follows some blackboard scribbling in which he reverses a sign in the equation for enthalpy to energy plus pressure times volume. Brainard names his discovery 'Flubber', which is a portmanteau of "flying rubber." In the excitement of his discovery, he misses his own wedding to Betsy Carlisle (Nancy Olson), not for the first time, but his third.

    Subplots include another professor wooing the disappointed Miss Carlisle, Biff Hawk's (Tommy Kirk) ineligibility for basketball due to failing Brainard's class, Alonzo Hawk's (Keenan Wynn) schemes to gain wealth by means of Flubber, the school's financial difficulties and debt to Mr. Hawk, and Brainard's attempts to interest the government and military in uses for Flubber.

    Shelby Ashton (Elliott Reid), who was interested in Betsy, is given his revenge by the Professor, who keeps on jumping on the top of Shelby's car, until it crashes into a police car, where he is given a field sobriety test.

    Looking for backers, he bounces his Flubber ball for an audience, but his investment pitch proves so long-winded that most of the crowd has left before they notice that the ball bounced higher on its second bounce than on its first. For a more successful demonstration, he makes his Model T automobile fly by bombarding Flubber with radioactive particles. Other adventures and misadventures result as Brainard using Flubber on the bottoms of basketball players' shoes (in a crucial game) giving them tremendous jumping ability; Brainard (at a school dance) making him an accomplished dancer

    Following his son's advice, the scheming Alonzo Hawk switches cars on the professor, with a car containing a squirrel and pigeons, to show off to the US government officials that Brainard's invention is a fabrication. Hawk then must be tackled by a full football team to bring him down after Brainard tricks him into testing Flubber on the bottom of his shoes. The Professor retrieves the old Model T from the warehouse, and Hawk is arrested for having a gun in his possession, when the car crashes into a police car. Eventually, Brainard shows his discovery to the government, after being scared by a missile in flight, and also wins back Miss Carlisle, culminating in a wedding at last.
