Floating Density Ball laboratory equipment • Compact benchtop design —Floating Density Ball: A hollow metal sphere that floats in cool water and sinks in warm water making the abstract concept of thermal density change immediately visible and memorable. The ball's density is precisely calibrated to sit at the boundary: cold water is dense enough to support it; warm water, less so. A simple, powerful demonstration requiring minimal setup. How to run the demonstration: Fill one 1000 ml beaker with cold water (ice water or
