Are we really clean???

Our darling condo has only a shower. So in order to wash the kiddies we bought this tub. Yesterday after a 3 hour stay at our town swimming pond the kids came home very sandy & gross. Elsa went in the tub first but Thomas didn't want to wait for her to finish so he ran in too.

My question is are they really getting clean or just sharing dirt. You know there is a little pee in the tub and a lot of sand.

I guess they come out a little cleaner then when they started right? ;-)
