The Physics of Human Sperm vs. the Physics of the Sperm Whale

This The Physics of Human Sperm vs. the Physics of the Sperm Whale video also includes:

Here is an unusual comparison: the swimming conditions of a sperm cell and a sperm whale. Introduce your physics class to the Reynolds number by sharing this video comparison during your fluid mechanics unit. Afterward, teach them to calculate the Reynolds number for other organisms to determine whether inertial or viscous force is dominant, or assign a laboratory investigation on viscosity of fluids.
