Color Changing Milk

By: Sophie, Emily, Kennon, Kori, Skylee,Hannah

Brief descriptionFood coloring starts in the middle on top of the milk then with a Q-tip and a little dish washing soap the color spreads quickly to the rim of the plate.

Materials

2% Milk

Dinner plate

Food coloring (red, yellow, green, blue)

Dish-washing soap

Q-tips

Step-by-step process

First, you poor the milk onto the dinner plate. Then you put one drop of each color of food coloring in the center of the milk. Next put some soap on one end of the Q-tip. Put the Q-tip into the coloring and watch the colors go.

Changes

You could use different liquids other than milk or you could use something other than dish soap. You could change the colors of the food dye also.

Why does it work?

It works because the fats and proteins in milk are sensitive to the surrounding solution which would be the milk in this case. The dish soaps bipolar characteristics weakens the chemicals bonds that hold the proteins and fats in solution.
