Convection of Liquids Glass Square Demonstration – 10" H Pack of 10 Physics Lab Apparatus by GSC International Inc.

Convection of Liquids Glass Square Demonstration – 10" H Pack of 10 Physics Lab Apparatus by GSC International Inc.

This bulk pack of 10 glass square convection apparatuses from GSC International is perfect for classrooms or multi-station labs, allowing multiple students to simultaneously observe convection currents in liquids. Each glass square demonstrates how warm liquid rises and cooler liquid sinks, making heat transfer concepts visible and engaging.

To perform the demonstration, fill each glass square 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. Convection currents become visible as the colored water circulates through the glass tube, illustrating fluid movement similar to a hot water system. (Heat source and support stand are not included.)
