Here is how to make a home-made hydraulic ram pump from scratch without sanitary products. | Interesting Engineering

Ram pump, also known as a hydraulic ram or hydram, is a water pump that uses the power of flowing water to lift a smaller amount of water to a higher elevation without requiring external energy. It works by using the "water hammer" effect, where a large amount of moving water is suddenly stopped, creating a pressure surge that lifts a portion of the water | FarmX
