We offer a fun experiment called “Exploding Colors” that represents the relationship between milk and common dish soap that can be found at your home! Milk has fat in it and the food coloring floats on top of the fat. The fat is all connected with bonds. Think of it like the little pieces of fat all holding hands with each other. Dish soaps are used on greasy or oily dishes because it breaks the bonds in fats allowing them to separate. Make sure to check out our experiments page for the full experiment!

First, we add food coloring to milk. This does not change the chemical reaction, but rather it allows for us to have a clear visual of what is actually going on when the experiment is done. When you add the dish soap to the milk, the fat separates and moves making your colors explode! As soap is added, the soap wants to bond with the fat molecules that are found in the milk, and it creates a beautiful reaction easily seen with addition of the food coloring.
