Professor Ned Brainard's discovery of flubber hasn't quite brought him - or his college - the riches he thought. The Pentagon has declared his discovery to be top secret and the IRS has slapped him with a huge tax bill, even if he has yet to receive a cent. He thinks he may have found the solution in the form of flubbergas, which can change the weather. It also helps Medfield College's football team to win a game. At home, his wife Betsy is jealous of the attention lavished on him by an old high school girlfriend.

How to Watch Son of Flubber Legally and Safely

If you want to stream Son of Flubber through reputable and legal services, there are a few good options depending on where you are. Subscription platforms like HBO Max, Disney+, Netflix, Amazon Prime Video, and Apple TV+ sometimes carry Son of Flubber films or related DC titles—though availability depends on your country.

If you’d rather not commit to a subscription, there are ad‑supported, free (but legal) platforms such as Tubi, Pluto TV, Peacock or Crackle (where available in your region) that occasionally host superhero films.

Lastly, don’t forget about library‑linked streaming options like Kanopy or Hoopla (if your library or university is registered), and official uploads by film distributors on YouTube—these can also give you legal access to classic movies.
