Bubble bath or great toy?

I usually let my son pick out which bubble bath product he wants when we buy it.Of course, he immediately gravitated towards the Lightning McQueen car!The back end of the car comes off to reveal a cap to open for the bubble bath.It smells good and bubbles up just as well as any other kids bubble bath, but the part that sold us was the container!The wheels turn very smooth and the car is very easy to push--full or empty.When the bubble bath was gone, my husband filled the car with water and gorilla glued the lid on--that thing is not coming off!With the car weighted down it rolls and rolls and rolls!My son can get this car from one end of the house to the other!What better way to recycle your bubble bath container than to play with it for hours?
