Viscosity Tubes

a few fluid-filled tubes propped at an angle, each with a metal ball inside
Tilt the tube and watch the metal ball fall.

Each tube is filled with a different fluid, and the metal ball inside will fall at a different rate in each one. The viscosity of each fluid is different, so each ball experiences a friction force of a different strength.
