Materials
Whole Milk
A baking pan
Red and blue food coloring
Liquid dishwashing soap
Directions
Pour some milk into the baking pan, enough to cover the bottom of the pan. Drop several drops of blue and red food coloring around the milk. Add a “squirt” or two of the dishwashing liquid and watch the colors burst and swirl. The dishwashing liquid separates the fat from the other liquids in the milk. If the fireworks slow down, just add another squirt of dishwashing liquid.
