Have you ever wanted to make something amazing? Well, now you can with the help of this Magic Milk Science Experiment. You can make it with the kids in your life and they will be amazed. This type of experiment is when you put dish soap and milk together.
You will see that the dish soap actually causes fat and water in the milk to separate from one another. Yes, you will totally see it spread apart. It’s one of those experiments that makes everyone good ooh and ahh!
Is Magic Milk considered a Chemical Reaction?
Yes, when Magic Milk is “made” it is considered a chemical reaction. Because the proteins and fats in the milk are sensitive to what’s in the soap, you will get a chemical reaction. Of course, not everyone thinks this is a chemical reaction because nothing is being blown up. STILL – something is reacting, which means it’s a chemical reaction.
Can you use water instead of soap?
The good news with the Magic Milk Science Experiment is that you can totally use water, yay! Keep in mind that the water isn’t going to have a chemical reaction. Although, you can get some really pretty colors happening in the water! Since water doesn’t have any fats or proteins though, nothing really happens reaction wise.
Your kids can still have fun and play in the magic water though. They will get some really pretty colors forming, which is always a lot of fun when you’re a kid and doing a science experiment.
What Happens When You Add Dish Soap to Milk?
When you add dish soap to milk, you are going to get this Magic Milk Reaction. The dish soap reacts fabulously with the milk and creates swirls of color. This is actually a beautiful science experiment that always wows the crowd.
Magic Milk Science Experiment
1 1/2 cups of milk
Pour milk onto a plate.
Drip a few drops of food coloring of choice in the center of the milk. You can get creative with where you drop the drops and space them out how you wish. (Note: Food coloring may spread out slightly as pictured.)
Place the cotton swab in the middle of the colors and watch what happens! You should see the colors start to spread out towards the sides of the plate and change over time.
Tip: Kids can take their cotton swab and “draw” or “swirl” in the colors. Eventually, the colors will mix together until the milk becomes one color.
If you allow the milk to sit a while before all colors are mixed completely together, you can see the milk change in neat ways as pictured here.
Watch over time how different things look! When complete, dispose of milk in the sink.
