These little guys are fun in a puddle, in a stream, in a pool, in a tub or in a container. Make one for fun. Or make a whole bunch and hold a cork boat regatta (that’s a boat race). All you need are a few corks, two rubber bands (I used some that came on the celery I brought home from the grocery store), a toothpick, and some foam or card stock. Watch this little video to see how!
