John F. Allen and Harry Jones discovered the "fountain effect", in which superfluid Helium flows up a tube and shoots into the air upon being exposed to a small heat source (the heat source in the original experiment was a flashlight that they were using to look at the apparatus). Allen also used a movie camera to film his experiments, such as the superfluid helium fountain (seen here). His was an early use of moving images to document experiments and inform students and the general public.
