Density ball is used demonstrate the effects of temperature and mineral content on density.
The metal ball will float in cold water, and sink in hot.
Flowing at normal temperature, sunk at 55℃ dia：100mm, made by heavy duty stainless steel.
The effects of salinity and temperature play a large role in the flow of earth’s ocean currents.
The Denstity Ball can be used by varying salt content as well as temperature, to show the effects on density.
The density of water is not constant but depends upon several factors.
