An indoor rainbow on a rainy day....a surface tension experiment

 This is an experiment perfect for a rainy day...and you have everything you need right in your cupboards.
You need:
Milk
food coloring
q-tips
dish detergent
a "deep" plate-suitable to hold milk
 Pour milk onto the plate and then add 3 drops of 3 different colors of food coloring to the center of the plate of milk.
 Dip the end of a q-tip into the detergent.
 Place the q-tip into the center of the food coloring and watch the magic.
The colors swirl and twirl and mix together creating a rainbow of colors.
And it also contains a science lesson about surface tension.
