STEM fun with rainbows! 

For kids ages 3 -10  interested in experimenting with color, try this science experiment to see the beauty of rainbows with walking water capillary action!  You will need paper towels, clear cups, and some food coloring... and a little  patience to watch and wait.  (See the YouTube link below for a tutorial.) Keep putting rainbow pictures in your window!  It is uplifting to see!
