the best $5 I've spent
This heavy duty plastic tub turns any table into a water play table for your kids.
So far, ours has been an ocean, a dinosaur habitat, a pony swimming pool, a Barbie beach, and a car wash/rock wash/toy wash. It's inspired hours of outdoor play, which is saying a lot given that we're already in triple-digit temps around here!
I found ours for $4.99 at the hardware store in the concrete/grout section.
