Demonstrates the convection currents in air. Comprises a sheet metal box with open sliding
glass front and two circular openings at the top for mounting glass chimneys.
On the inner side, below each chimney, a candle holder is mounted.
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.
