Precipitation

Rain in a jar

To make this you will need:
A jar
Water
Shaving cream
Blue dye
5 ml syringe

Method:
First we put water in our jar. Then we put a thin layer of shaving cream. When this was ready and covering the water we carefully dropped 5 drops of blue dye in and watched what happened.

It was like slow motion rain. The blue dye acted like precipitation and slowly went to the bottom of the jar.

This is easy to do if you want to try it at home.
