This smaller-sized convection apparatus is designed for easy use in classroom settings, providing an efficient way to demonstrate convection heat transfer principles. Unlike standard gas convection apparatus, this compact model (measuring 4"x6"x4") is ideal for convection experiments in smaller spaces. The apparatus includes a durable metal box, a sliding front door, two glass chimneys, and a secure candle holder for safely demonstrating heat transfer with tealight candles.Please note: Candles are not included.Perfect for teachers and students, this apparatus allows for hands-on learning of convection currents and is a must-have for science classrooms. It is designed to show how heat moves through fluids, providing a clear visual of the convection process in action.
