Product Description
Aluminum density cylinder floats or sinks in water depending on the water density. The density of water on the other hand depends on the water temperature and the amount of minerals in water. The purpose of this product is to demonstrate the changes in water density depending on the temperature or depending on the minerals in water. Changing the water density has many industrial applications. In many cases the application is material separation by floating them or by sinking them to the bottom.
Aluminum density cylinder floats in cold water, but sinks in warm water. Includes activity guide. Measures 0.65" diameter x 3.5" long. Weight is 0.5 oz.
The density of water is not constant but depends upon mineral content, temperature and pressure
