I have created some animations using the fluid simulator in blender before but this experiment is the first one I really like. The material is a mixture of a glass node, a transparent node and a glossy node. The fluid was rendered with a resolution of 300 and a subdivision of 2. If you want to render it your self - be warned it takes some time.
