Crayola has come out with these water color changing tablets. At first, I thought, "No way! This spells disaster!" But I decided to give it a try and put them in her Halloween basket. I'm sure 2-7 years olds would be more impressed than Grace (What am I talking about?? This 26 year old was impressed!), but she likes them and even repeated the word "blue" after me. Grace does not come out of the bath tub with any color on her skin and they don't stain your tub so I highly recommend them.
