The Surface Tension Dance - Spontaneous motion of dyed liquid droplets


I love it when science and art collide.  OK, this one caught me off guard.  In the video below, researchers Nate J Cira and Manu Prakash, from Stanford, show little drops of liquid dancing around spontaneously on a glass surface based on surface tension.  When sped up, these little buggers look like they are dancing around on the glass slide.  There is a peculiar imbalance between the long distance forces and short distance forces that make the motions quite complex.  Watch and enjoy.
This work is currently being presented at the American Physical Society's annual Division of Fluid Dynamics Meeting.  More info on this work in particular at Physics Central.
