Ventilation Apparatus
Catalogue No: 1061060
Demonstrates the principle of ventitation convection currents in air. Comprises a sheet metal enclosure with open sliding glass front and two circular openings at the top for mounting glass chimneys. Air heated by a candle placed beneath one of the chimneys with glass door closed, causes the flow of convection currents, which can be observed by bringing a smoldering string near the top of other unheated chimney. Supplied without candles.
