THE GRAND MILK EXPERIMENT
Ingredients: milk, pie pan, food coloring, dishsoap, Q-tips
Preparation time: 3 minutes
Experiment time: until you get bored
Put milk in pan. Have children add food coloring.
Dip in Q-tip. Nothing happens.
Add droplet of dishsoap to Q-tip and VOILA! Color explosion. From what I understand, the milk's fat molecules are repelled by the soap molecules, and we see the action through the food coloring molecules.
And again, making pretty patterns.
What happens when they both do it at once? Two polar vortexes!
