Heron’s fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron of Alexandria. Various versions of Heron’s fountain are used today in physics classes as a demonstration of principles of hydraulics and pneumatics. Here is a video to make Heron’s fountain at home using 3 plastic bottles, straws and basic tools. This is a non-stop fountain that runs on its own without any pump or support. A very educative and enjoyable activity for all ! Strongly recommended for students !
