Important Setup Notes:
Don't spill the glycerin - it's difficult to clean up.
Setup:
- Fill non-glycerin cylinder with water so that fluid height levels in each cylinder match.
- Place cylinders on table side-by-side.
- Have marbles ready to be dropped.
Demonstration:
Grab two marbles of identical size and weight. Hold one marble in each hand above each cylinder. From the same height, drop each marble at the same time, and observe the velocity differences.
