This is a great story about animals shaking water off their fur. The video (no audio) gets technical in parts with Free Body Diagrams and equal force equations, but as an engineer, it was fascinating. Essentially the force needed to shake a drop of water out away from the body, has to be equal to the force of the shaking at the place where the drop is (obviously). What may not be so obvious is that bigger animals can shake slower compared to smaller animals, and the equations in the video explain why.... Check it out!

Honestly this was much more interesting than the foodscapes. Why didn't I think of this a project when I was in college???
