Heron's fountain is a hydraulic machine invented by the 1st century AD inventor, mathematician, and physicist Heron (or Hero) of Alexandria. [ 1 ] Heron studied the pressure of air and steam, described the first steam engine , and built toys that would spurt water, one of them known as Heron's fountain.
A syringe-like device was described by Hero to control the delivery of air or liquids. [17] A stand-alone fountain that operates under self-contained hydro-static energy; now called Heron's fountain. A cart that was powered by a falling weight and strings wrapped around the drive axle. [18] A kind of thermometer has been credited to Hero.
Heron's fountain is a device invented by Heron of Alexandria that consists of a jet of fluid being fed by a reservoir of fluid. The fountain is constructed in such a way that the height of the jet exceeds the height of the fluid in the reservoir, apparently in violation of principles of hydrostatic pressure.

Heron's siphon is not a siphon as it works as a gravity driven pressure pump, [63] [64] at first glance it appears to be a perpetual motion machine but will stop when the air in the priming pump is depleted. In a slightly differently configuration, it is also known as Heron's fountain. [65]
Invented by Heron based on Ctesibius' double-action piston pump. [33] Allowed for more efficient fire fighting. Vending machine: 1st century BC The first vending machine was described by Heron of Alexandria. His machine accepted a coin and then dispensed a fixed amount of holy water. When the coin was deposited, it fell upon a pan attached to a ...
