I have been loving the invention of this Crayola product for years. The kids love it and I am always tempted to color my own bath water!!
I think these color dotz are a great alternative to bath toys that get grimey and all ridden with bacteria. They aren’t that spendy, $5 for 30 baths. We like to mix colors and see what new color we get, so some math is involved. Give them a try. Even if you don’t have kids, use it in your next bath!
