Magic Fountain

How to make a magic fountain with daily use objects.

When you put some water in the fountain, it starts to flow.

It is amazing to see the surprised reaction of kids and adults.

This experience is based on heron's fountain invented by the 1st century AD inventor, mathematician, and physicist Heron of Alexandria.

For this instructable you need :

- 3 plastic bottles with caps
- 3 long straws
- Glue gun
- Drill
- Cutter

First of all, glue a bottle cap on the bottom face of a bottle.

Then drill two holes in it.

Finally cut the top of a bottle.

This will be the upper part of the fountain.

Glue two bottle caps together and drill two holes in it.

This will be the middle part of the fountain.

Take the three long straws and cut them as followed :

- From the bottom of the intermediate bottle to a little longer than the upper bottle.
- From the bottom of the lower bottle to the bottom of the intermediate bottle
- From the top of the bottom bottle to the top of the intermediate bottle

Glue the straws using a glue gun.

Fill the fountain with water from the top of the fountain.
For a better visual effect, I recommand to use dye to have a colored water.

Put the fountain upside down. This will fill the intermediate bottle.

Then put some water from the top, this will activate the fountain.
