Convection and Ventilation Box
This is the standard device for demonstrating convection currents and ventilation. When a lighted candle is placed under one chimney and a smoking paper is held over the other, the convection current may easily be seen. The precepts of ventilation may also be shown by covering the chimneys and removing, in various combinations, the corks in the side panels.
Dimensions given do not include height of inserted chimneys.
