The interesting thing to me is the technology they use to get the pictures. When I was an undergrad, I spent a summer working on a project that took 2000 frames/sec of crack propagation. To do that we had a 5 foot in diameter cylinder that was lined with a long strip of film. A rotating mirror in the center reflected the image onto the film. The "camera" was triggered when the crack broke a wire. The turbine spinning the mirror was so delicately balanced that we all had to stand in another room while it was in a picture taking cycle, lest it explode.
