The Heron’s Fountain is a great physic experiment really useful for a science fair. The Heron’s fountain shows how to provide power using water and gravity. This is the result of potential energy.
The objective of these physic experiments is that students understand the principles of Pascal and Archimedes easily.
Herón de Alejandría, according to several written sources, introduced many models using floats, levers and pulleys to move statues and compressed air to produce a whistling sound. He wrote pneumatics, a treaty that included descriptions of traps, valves, pumps and a rudimentary steam engine. One of these devices was a source who worked “under pressure” with no additional energy source, this source would be called the Heron Fountain.
- Three plastic bottle
- Caps or corks
- Thin tubes or hoses of latex
Heron‘s physic experiment
1) Make the outline as it is shown in the figure:
2) It has been built an Heron fountain with three plastic bottles conveniently linked by tubes.
3) Cut to size pipes and holes to make bottle caps, make sure to do the experiment when the bottles are sealed, for this we use clay.
3) The intermediate container is filled with water and the bottom vacuum.
4) The above container is cut in half.
5) Water is poured above the container which presses the air in the container below that drives the water up the intermediate vessel for water leaving a pump.
In conclusion of this experiment say that the air is capable of raising the water provided it is in a sealed enclosure.
