Convection in Liquids, C3-2900.00, £8.95
Very simple apparatus for clearly demonstrating that hot liquid rises.
apparatus is filled with water and a candle, which is a nice gentle
heat source, is placed under one limb. A few drops of dye are then
added to the water. As the hot water above the candle rises it pushes the dye round the apparatus.
This simple and effective apparatus helps to promote a hands-on approach to learning.
