Shaving Cream Rainbow - Sensory Play

To create the giant rainbow, I used seven cans of shaving cream.  I bought mine at the dollar store so it cost me less than $10.  

I then dyed the shaving cream using food coloring and liquid watercolors.  The orange and blue were dyed with liquid watercolors as they happen to be the only two colors I have on hand.  I am buying them one at a time with the 40% coupon from Michaels, so it's taking me awhile!  Don't judge...haha.  Anyway, I found that the shaving cream that was colored using the liquid watercolors was much more vibrant.
