Food Coloring, Fluid Dynamics, and an Awesome Lab Demo

This video starts out in a fairly innocuous way. Some colored drops of corn syrup are slowly mixed by a rotating cylinder. Ho-hum, right? 

Well, wait until you see what happens when the handle is turned backwards. This is all a demonstration of how certain liquids can flow without turbulence, and how delicate hands can disassemble and reassemble the “sheets” of colored liquid. 

Wow, indeed.

    I have used this video whenteaching laminar flow and viscosity before. It is fascinating. I must add this to pinterest!
