Fluids can form droplets that pinch off from each other in many  situations ranging from ink jet printers to the kitchen sink. The phenomena that occur a few microseconds from  pinch-off involve a balance of surface tension forces, inertia, and viscosity. Droplet pinch-off is an example of  a non-linear phenomenon that leads to finite time power law singularities and striking geometric structures  that obey scaling relations  and  have universal behavior , in rough analogy with thermodynamics near the critical point. I will discuss the mathematics used to describe these singularities, as well as recent experiments  using high speed video to study pinch-off in liquids and bubbles in 2D and 2D.
