What you need:
- A saucer
- milk (not skim)
- food coloring
- dish soap
What to do:
Pour a bit of milk into the saucer, add several drops of food coloring in different colors.
Carefully pour one drop of dish soap into the milk and see what happens!
You can add more drops of dish soap and/or more food coloring to get different effects.
What happens: The food coloring sits on the fat molecules in the milk. When you pour the dish soap in, it breaks up the fat and the food coloring along with it. We tried this several times doing something a bit different each time and we got really cool effects!
