This video is of a strange phenomenon called the Kaye effect. It includes high speed video of the effect, and a demonstration of their mathematical analysis of the effect, and their prediction and verification of the effect.

The Kaye effect is an incredibly bizarre phenomenon. Basically, if you take a substance like liquid shampoo, and allow a thin stream of it to pour down from a height onto a smooth surface, the stream will periodically "bounce", producing a stream leaping up from the point of contact. Watch it - it's intriging and sparks a mental challenge to define the physics in a new arena based on the strange phenomena occuring within our solar system
