Chimney for Ventilation Apparatus-For demonstrating the phenomenon of
convection in air and the principle of room ventilation. Consists of an
enamelled metal box 20 x 10 x 10cm (L x W x H) having a sliding glass door and
two glass chimneys. When a candle is paced under one chimney and a smouldering
tape or splint is placed underneath the other chimney, the flow pattern of
smoke dramatically illustrates the formation of convection currents. Candles
are not supplied.
