Heron’s fountain

Heron’s fountain is a water transportation system that is used as a fountain. Heron’s fountain was developed by the Greek engineer Heron, approximately 2,000 years ago.

If we follow the course, we start when the top bottle is full and the bottom bottle is empty. All this is because the lower bottle is filled by tube A, which compromises the air in the bottle below. The pressure affects the bottle above via tube B, and the water rises through tube C until it erupts in the top container. Tubes D and E empty the bottom container and fill the one at the top.
