# Herons Fountain Model for school science exhibition

## Introduction:

Herons fountain model is named after the physicist and mathematician Heron of Alexandria. It is a hydraulic machine is a steam engine that emphasizes on the study of pressure of air and steam.

There are many variations of this model that are studied today which explains the theory of hydraulics and pneumatics. Herons fountain can be built with help of three simple things, basin, water supply and air supply.

To start the action in the fountain, first, we need to make sure to hold the air in the air container and water in the water container.

Next step is to pour water into the basin and the water will flow from here to the air container.

This is because of the gravitational force. And then it moves to the water container increasing the pressure in the air container.

This increased pressure forces the water out of the container as a fountain in the basin.

In this video, we show the herons fountain model as an experiment with the help of very simple materials that are easily available. This experiment should be done only with the help of your teachers or parents.

## Materials used:

1. Two bottles
2. Bottles caps
3. Hot glue gun
4. Straws
5. Tea cup
6. Any tool or machine to drill holes

You use the resource/tools page section to find the tips where you can buy these materials used at a reasonable cost.

## Detailed Video Show How To Make Herons Fountain Model for school science exhibition

1. Who invented Herons fountain?

A. Herons fountain was invented by mathematician and physicist Heron of Alexandria in 1st century AD.

2. What is the theory behind Herons fountain?

A. Herons fountain experiment displays very basic principles of physics. It shows how potential energy can provide power using pressure, air, water and gravity.

3. What are the tools or machines that are developed with Herons experiment as reference?

A. Water heater or geysers work on this science of Herons fountain. The thing that makes the geysers different from the usual Herons fountain is that the water is spouted discontinuously depending on the temperature of the water.

### Conclusion:

Herons fountain is a simple experiment that explains the physics of hydraulic machines.

When the water flows from the high gravitational force to low gravitational force under the air pressure, it causes the water to flow or spout.

This is not a perpetual process because, when the water flows from the fountain higher than its height, it automatically leads to decreased pressure and thus spout height and quantity of water decreases.
