After painting with cars, we needed to clean them, so I filled up the water table with soapy water, a sponge, and an old toothbrush. Trip collected the painted cars as well as some others and got right to work.
The sponge was his favorite cleaning tool and he was quite meticulous.
He liked to make the cars splash in the soapy water.
His concentration was only momentarily broken by the sound of a plane.
"Look, Mommy, a plane!"
Then, it was right back to work, this time to give the cars a shower.
