Here's a weird behavior of complex liquids, called the Kaye Effect [wiki], named after British engineer Arthur Kaye, who first discovered it in 1963. When a think thin stream of viscous fluid is poured onto a surface, a stream of jumping liquid can be seen!

Fascinating. Amazing how high-speed cameras put phenomena down to our speed so we can observe it. I wonder how many small processes go unnoticed because they're outside of our reach in being too small, too fast, too large, etc...
Some kind of "moving-surface"?
