Food Coloring Explosion Activity - Food Coloring, Milk, Dish Soap

Here is a fun activity you could use for the Webelos Artist Activity Badge #4 - List the primary and secondary colors.  Explain what happens when you combine colors.

We did this as a lunch date activity for our kids but I'm sure the Webelos would love it too.

 
First you put milk in a dish, we used disposable aluminum pans. Then drop in a few drops of food coloring, dip a toothpick in dish soap and touch the drops of food coloring with the toothpick. The food coloring explodes in the dish.

If you do this for the Artist Activity Badge, you could drop in food coloring of the primary colors. After you let the boys experiment with the color explosions, have them mix the primary colors with a spoon to get secondary colors.
