Son of Flubber

Professor Ned Brainard unveils Flubber, a versatile energy-rich substance with strange properties. He hopes it will bring wealth and scientific fame, but the discovery quickly draws top-secret status from the Pentagon and attention from the IRS. Ned worries about the implications of controlling such power.

Ned theorizes Flubbergas could alter the weather. He tests a ray projector and makes it rain in his kitchen and garage, demonstrating the potential of his invention. The effects only work on makeshift clouds, hinting at bigger challenges.

When faced with real clouds, Flubbergas fails to produce rain and instead shatters glass across town. The unexpected destruction tempts lawsuits and draws the ire of property owners. Ned's experiment becomes a liability, increasing pressure on him.

Alonzo P. Hawk targets Ned after the glass incidents, threatening legal action and seeking to close Medfield College. He proposes a partnership in a glass company scam to recoup losses and leverage Ned's work. The threat underscores the conflict between Ned's genius and the business world.

At home, Betsy grows weary of their financial stress and watches with worry as Shelby's attention to Ned resurfaces. The romantic triangle strains their marriage and tests Ned's focus on his experiments. Betsy fears the consequences of his obsession.

Ned uses Flubbergas to rain inside Shelby's car, complete with thunder and lightning. The car fills with water and crashes into a police car he had previously wrecked in a prior adventure. The stunt demonstrates Ned's lack of control when emotional stakes rise.

Flubbergas helps Medfield win a football game against Rutland, boosting the team's morale and validating Ned's work in the eyes of townspeople. The victory heightens public interest in the invention and its potential uses. The moment shows the practical side of Flubbergas.

Following Ned's arrest, Betsy ends her involvement with Shelby and chooses her husband. The breakup marks a turning point toward family stability and reconciliation. Shelby's influence over the couple fades as trust is rebuilt.

Ned faces multiple property-damage lawsuits as prosecutors push him to abandon his experiments. The county agricultural extension agent appears in court and testifies that crops around town have accelerated growth, attributing it to Dry Rain. The unexpected evidence shifts the courtroom dynamic.

The court is convinced by the Dry Rain findings and Ned is acquitted. The verdict clears his name and allows him and Betsy to reconnect without legal clouds over their future. They resume their life together with renewed optimism.

Driving home in their flying car, Betsy tells Ned she is crazy about his science. They share a kiss as the tension dissolves and the couple looks toward a brighter future. The scene reinforces the film's light-hearted ending.

In the final image, a football filled with Flubbergas launches into outer space. The absurd ending highlights the whimsical potential and the far-reaching reach of Ned's invention. The audience is left with a playful sense of wonder about science gone awry.
