Fluids are a constant source of inspiration for high speed photography. Water and milk are two of the common liquids around us every day, but still their complex behavior is a source of wonder. Fluid scientists are still pioneering some of the basic equations that are responsible for the complex motion of fluids. In these pictures a drop of liquid is falling into a container of liquid. The first falling drop creates a recoil splash that shoots up out of the container. Just when the recoil droplet gets to the top of its motion a second falling droplet collides. The timing often happens by chance when pouring liquids, but here it is controlled with a microprocessor so each collision can be studied and photographed in detail. The motion is once again frozen in time with the help of a 1/60,000th of a second flash.
