This is an easy, fun and potentially messy activity. You can do this inside in your kitchen sink while you prep dinner (that’s what I did today), you can do it outside on a warm day or you can do it at bath time. All you will need is some cars, soap (we used bubble bath) and a sponge. Using a tray like I did is optional, but it may keep it from getting too messy or not, LOL.
