To show how water rises in different types of soil
Place about 15 cm of dissimilar types of soil in a series of lamp chimneys after tying a piece of cloth over the end of every chimney. Such soil samples as sand, loam, gravel (fine), clay, etc. may be used. Next stand the lamp chimneys in a pan which having about 3 cm of water. Observe the type of soil in which water increases highest because of capillarity. Clear plastic drinking straws can also be used for this experiment.
