What you’ll need: Spray bottles; buckets; sponges; dry rags; liquid soap; toy cars; towels
Directions: Round up the plastic spray bottles and buckets you have lying around the house and fill them with water. Set up the bottles, sponges, dry rags outside and let the kids "wash" their mini toy cars, wagons, bikes and ride-ons.
Why they'll love it: Two things he loves -- his toy cars and getting soaked. Remember the towels!
