Scrappy cartoon from Charles Mintz of Columbia Pictures. In this one, mad scientist Hugo Plotz experiments on the boy character in a water bowl by first turning him into a fish and then an old man. When his little brother comes in, Hugo then turns them into babies. And then when they go back to normal, they travel into the future, all the way to 1990. There they encounter people in propeller hats and attempt to rescue a girl from Plotz.

How to Watch The Great Experiment Legally and Safely

If you want to stream The Great Experiment 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 The Great Experiment 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.
