Science videos can be difficult to understand, badly produced and and slow-going. Not this one, because really it's just a compilation of cool fluid dynamics phenomena, stitched together into a wonderful, mesmerising three-minute clip.
Called Compressed Experiments, the video was created by Kim Pimmel and is set to the Katamari Damacy Theme. It's virtually impossible to choose a favourite part -- but if pressed, I'd have to say that I love the micro-jetting at 1:16, or that wonderful propagation of I-don't-know-what at 2:15. Enjoy.
