1. Pour milk into the plate (just enough to fully cover the bottom). Drip 5 drops of each food color into the middle of the plate of milk.

2. Pour dish soap into a small cup. Dip your Q-tip into the soap and dab off the excess. Count to 3 and dip the soapy Q-tip into the middle of the milk plate.

3. Hold the Q-tip there and watch the colors move around!

4. Optional: Warm milk works better. Microwave it for 25 seconds before pouring on to the plate.

Picking Up S.T.E.A.M. Milk contains fat molecules. When we say “2 percent” milk, we are saying that 2 percent of the milk is made of fat molecules. Soap is really good at cleaning things like dirt and oils off our hands and clothes. It does this by surrounding fats, oils, and dirt molecules and lifting them off our hands and clothes. When we add soap into milk, the soap molecules start moving around as they interact with the fat molecules. It’s almost like they are dancing around. Since milk is white it is really hard to see, we add food coloring to see the process in action. The food coloring gets dragged around as the milk molecules move.
