So the kids want to make a mess, and you’ve hit your cleaning quota for the day? Bring it to the bath. The marketing minds at Parents magazine gave us these genius ideas for letting kids run color-wild while containing the #HappiMess in the tub.

1. Make Masterpieces

Give “watercolor” a whole new meaning when you transform bathtub walls into easels. Just hang large sheets of paper around the tub, then let your pint-size Picassos get to work with washable paints. When they’re done, keep the paintings… and use a hand shower to rinse any excess paint from the bath.

2. Mix the Crème de la Color

Mix one to two drops of food coloring with a dollop of shaving cream to make “paint” that kids can use like fingerpaint on the side of the tub. It’s easy to make—and just as easy to wash away.

3. Create Color Dust

Add a small handful of crushed sidewalk chalk to the tub along with your kids’ favorite bubble bath, and watch your little ones create colorful bubble beards and wacky rainbow hairdos. When they’re done, just turn on the shower to make the bubbles disappear.
