1. DISCOVERY TUBES
This project is very popular on the internet and I can see why. The combination of milk, dish soap, and food coloring makes for some color swirling magic! You can even dip paper in the milk to make a milk “print” to keep! See how we did it here.
The basic recipe for this is originally from The Usborne Big Book of Science Things to Make and Do, a book I highly recommend you have in your library, there are many more fun ideas like this one! We modified it to give it a rainbow twist!
Fill the jar halfway with vinegar, then add a few drops of one color of liquid watercolor/food coloring and some glitter. Squeeze in some dish soap, stir, and place the jar on a tray. Now have your child add in a heaping teaspoon of baking soda, stir again, and watch the foaming begin! The soap makes it foam rather than fizz. To keep the reaction going continue adding baking soda and vinegar when the foam starts to slow. To make it change colors, add a tablespoon of vinegar mixed with one color of liquid watercolor/food coloring every so often. Make sure to dump the colored vinegar into the center of the brew.
Tip: Stir It! My kids discovered that the more they stirred the mixture the faster and crazier the reaction! Did you hear the screams of delight in the video?
