There has been a bit of this:
I love summer for all the usual reasons: warm weather, gardens, ice cream, lemonade, and swimming. But I also love it for the opportunity it provides for easily-cleaned messy art and messy play (or messy art play, as it seems to become.) What started out as marble painting in the turtle pool quickly became fingerpainting, followed by painting with feet, and ending with a nice round of painting one's entire exposed epidermis. No worries. That's what hoses are for.
