Density sphere

The density sphere is an educational instrument designed to demonstrate the relationship between the density of a liquid and its temperature. This experiment allows students to observe how the density of water changes with temperature and how this affects the buoyancy of an object.

Features:
- Hollow sphere made of copper, ensuring durability and resistance to corrosion.
- The sphere has a sealed mouth, ensuring that there are no leaks and allowing predictable behavior in experiments.
- Specifically designed to float in cold water and sink in hot water, illustrating the principle of density and temperature.

Technical specifications:
- Material: Copper.
- Condition: Hollow, with a sealed mouth.
- Floats in cold water; sinks in hot water.
