M&M science experiment for kids. Learn how to make a rainbow w/ an easy rainbow science experiment. Fun STEAM activity for toddlers and preschoolers.
I had seen this rainbow M&M science experiment everywhere but my son hadn’t tried it yet.
I’m so glad we did this week and had a lot of oooohs and aaahs.
A morning cycle that your child can regularly follow is one of the best parenting tips you’ll use in your entire parenthood. My son uses the same schedule when getting ready for school in the morning but even if your child is at home you need this.
Doing an experiment is so much more fun than just seeing or knowing.
Save for later.
M&M Rainbow Science Experiment
All you need for this experiment is a plate, a glass of water and M&Ms.
Open your bag of M&Ms into the plate.
Have your child arrange the M&Ms on the plate in a circle.
Let them enjoy the leftovers.
Now pour a bit of water slowly into the plate with a steady hand.
What happens when you put an M&M in water?
The rainbow colors of your M&Ms start moving down the center of the plate and if you don’t move the plate, they don’t bleed into one another and stay separated like this for quiet some time.
Why do M&M colors not mix in water?
I found this interesting article you can read about this, there’s an interesting discussion going on in the comments.
Why does an m&m dissolve in water
After we completed this experiment, when we picked up the candies, their lower coating emerged in the water had completely dissolved and was gone. You could see the brown chocolate inside. This happened because the coating was made of sugar which readily dissolves in water.
m&m science rainbow makes a great addition to your STEAM activity for kids collection so do save it on Pinterest for later.
Would this rainbow science experiment work with skittles too?
I saw people do further experiments by using skittles, M&Ms, and other colored candies all at the same time. If you have older kids, this can be a great idea you can try together and brainstorm on why one dissolves faster, better, neater than others.
I hope you enjoyed this melting m&m science experiment as much as we did and you try it with your kiddos this week.
