Convection of Liquids Glass Square Demonstration – 10" H Physical Science Heat Transfer Apparatus by GSC International Inc.

Convection of Liquids Glass Square Demonstration – 10" H Physical Science Heat Transfer Apparatus by GSC International Inc.

This glass square convection apparatus from GSC International is a classic physical science demonstration tool used to visualize convection currents in liquids. Perfect for classroom heat transfer lessons, it helps students clearly observe how warm fluid rises and cool fluid sinks—just like circulation in hot water systems.

To perform the demonstration, fill the glass apparatus with water and a small amount of food coloring, then apply gentle heat to the bottom corner using a low-temperature heat source such as a candle. As the liquid warms, convection currents become visible as the colored water circulates through the glass tube. (Heat source and support stand are not included.)
