In this spoof of public-school educational films, young Mary Jane asks the question, "What is gravity?" After asking various (dysfunctional) family members without success, she then asks Dr. Waxman of the Karl LaFong Foundation for Gravitational Research (motto: "heads in the clouds and feet on the ground"), who explains that gravity is caused by a substance named GR12. Unfortunately, the world is running out of GR12. The cartoon character Jiminy Gravity then explains (in song) how we can conserve gravity with such practices as sitting on the floor and carrying helium balloons. Written by Anonymous

Did You Know?


Initial prints of this short film featured a scrolling cast list which credited performers Michelle Stacy as Mary Jane and Mitzi McCall as Mother. Later prints presented the cast in two still screens, with Mary Jane credited as "Herself" and Mother credited to "Lil Cocker." Most likely this was due to both actresses being members of SAG and the short's non-union status. See more »

Ah, the '70s
3 March 2016 | by Mr-FusionSee all my reviews

Take a cute kid, goofy sight gags, a surprise pair of boobs and an animated Jiminy Cricket mascot and wrap it all up in a kitsch '50s classroom science video and you've got "Gravity". It's a charming imitation that makes those musty educational movies enjoyable. It's got a nice helping of adult wit, too; kinda sneaks up behind you. This short became a running gag at the Ohio Sci-Fi Marathon many years ago (hopefully, it still is), and Big Sister was even inducted into the Marathon Hall of Fame. All it takes is a bleary-eyed audience and a topless character is suddenly a meme.

Anyhoo, I just found this movie online (artifacts like these are why I love YouTube) and it brought back memories. It's definitely worth a watch and I enjoy this thing as an obscure piece of pop culture.
