Take at look at what these kids have done

I hear them playing quite quietly while I am in the bath, I know their playing with their cars, however it seems to be toooo quiet. I can hear the cars being pulled out of the containers and know their getting them allllll out. Oh no - it means a big cleanup. After I get out of the bath, I went and took a look at what I knew would be some handywork. You know you just get the feeling.....
.... still i couldn't resist taking the photos.
