This rainbow milk science experiment is popular around the web. And for good reason.
Also called milky fireworks, erupting colors, magic milk, tie-dyed milk, and more, this very possibly both the easiest and most amazingly beautiful science experiment out there.
It is so super awesome and kids LOVE it!
Am I going a little over the top? I guess adults love it, too.
We have done this one before. More than once. But it never gets old.
This time we did the milky fireworks on top of our simple DIY light table (simply a clear plastic storage bin from Target with a string of white Christmas lights inside) which added an extra level of beauty to the experiment. It was lovely to see the light shining through the milk, the colors, and the magic!
Ready for the how-to and photos of the beautiful process?
I even embedded a couple of my instagram videos of the magic milk in action, since still photos can’t do it justice.
The Awesome Rainbow Milk Science Experiment
- Whole milk
- Shallow dish
- Food coloring (or Liquid watercolors with droppers as we did last time)
- Liquid dish soap
1. To set up for this activity, assemble food coloring, a small bowl of liquid dish soap, and some Q-tips then pour a thin layer of the whole milk in a shallow dish. As you can see, we did this science experiment over our light table this time around, so used glass baking dishes. All the better to let the light shine through, my dear.
2. To begin, squeeze droplets of the food coloring on the surface of the milk. One color or several colors.
3. Next, dip a Q-tip in the dish soap and then in the milk, preferably in the center of a spot of food coloring.
Watch the colors explode all over as the detergent interacts with the fat molecules in the whole milk!
Here are a couple of brief videos I took of the beautiful erupting colors in motion. I shared both on Instagram when we did this experiment.
Repeat steps 2 and 3 as often as you like until you end up with muddy milk.
If you’d like to keep going (my kids always do), discard the muddy milk then add another thin layer of milk and begin again.
So tell me… Have you tried this rainbow milk science experiment with your kids yet?
If not, you MUST do it asap!
If you have, you must do it again! Preferably asap.
It’s that good.
