Kids Science Experiments - Hose Pipe Rainbow
 
Make a Water Hose Rainbow

Materials you will need:

• A Sunny Day
• Running Hose Pipe

 
Steps
 
This is a great experiment to do outside on a hot sunny day.

It is very easy and the only things needed are a garden hose pipe with running water on a bright sunny day.  

This is also lots of fun for the children.

Steps:

1.  Stand with your back to the Sun.

2.  Spray water from the hose pipe.  (Place your thumb over the hole at the end of the hose to get a spraying effect).

3.  Watch the spray against a dark background (grass, hedge or a wall).

Can you see the different colors?  

Red, Orange, Yellow, Green, Blue, Indigo and Violet make up the colours of a rainbow.  

Light bends and slows down as it goes through water.  

Each colour of light bends at different angles, therefore you can see each color separately.
