Off the top of my head use the antique sash weights as;

1. Weights for Hall or dynamics carts for conservation of momentum, or
acceleration labs.
2. Weights for demo Atwood machines.
3. Bobs for long pendulums to tell time by earth rotation
4. Weights hanging at ends of sonometer wires to provide tension
5. Use them instead of barometers to measure heights of buildings
