Episode 55: Mountain Spring Pipe

In this episode, the science teacher shows kids the principle behind siphoning. Liquid moves from an upper reservoir to a lower reservoir because the pressure of the liquid in the end of the tube is greater than the surrounding pressure in the lower reservoir. When the water level of the two reservoirs are the same, and their atmospheric pressures are equal, the siphoning stops. Also, if air is in the tube, then the water would not flow. That’s why the villages always need ventilation pipe to discharge the air for the water to flow smoothly.
