Pour water into the large tube. Then compare the water levels in the four tubes of different shapes.
The communicating vessels make it obvious that the water rises to the same level in all tubes, regardless of the water volume and shapes of the tubes. This principle is used, for example, when water is to be transported from a municipal water tower to properties in a town.
Material: Tube made of glass, holder made of wood.
Dimensions: Glass tube 14x12 cm, holder 24x11 cm.
