We hopped in the tub with our suits and started making some crazy bubbles. We cut off the bottom of a water bottle and we used some old wash cloths and used a rubber band to put them on the end of the water bottle. The kids then dipped the washcloth in some water to get the wash cloth wet and then we dipped it in some bubble bath and blew in the top of the bottle to make some bubbles. Such fun!! We found the idea here.
