Rainbow Wizard's Brew

Materials: Baking Soda, liquid watercolors or food coloring, glitter, dish soap, vinegar, clear container, small plastic containers, tray 

Fill the container 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 container 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.
