How to catch a rainbow

B, 4 years old, is allowed to watch a tv show after doing his homework.  This week he choose a recording of Cybercase.  The subject?  RAINBOWS! 

Science Experiment: How to catch a rainbow.

This is one of the coolest experiments I've done with B (4 years old).  You will need 1 cup of milk, food color dye (preferably the primary colors), and dish detergent.

1.  Pour 1 cup of milk in small bowl.
2.  Drop about 3 drops for each color of food dye in a triangular pattern like we did below.

3.  Pour a small amount of dish detergent in the center of the bowl. 

The detergent floats on tops of the milk to mix the colors together. 

 I had B fill out a worksheet found here: http://www.kidzone.ws/science/rainbow.htm  He usually doesn't like doing worksheets but he was actually excited about this one.
