The biology department had boxes and boxes of those little pipettes, but they were plastic and would not sink, so we used metal washers (instead of the nut), because we could add or subtract washers for the ideal buoyancy.
Usually, they are designed to sink when we squeeze them. If you want to see how to make one that RISES when you squeeze it, let me know. 🙂

I was having so much trouble getting a Cartesian diver to work, and your photos and “troubleshooting” section helped me persevere. Works now! Thanks again!

A similar activity involves creating a Cartesian Diver. […]
