This recipe is a winner. It's easy to mix up--and inexpensive to boot. Simply stir together 6 parts water, 2 parts Joy dishwashing liquid (this brand works the best), and 3/4 part corn syrup. Store in a covered container.

Have your kids try experimenting with a variety of homemade bubble wands: pipe cleaners bent into interesting shapes, cookie cutters, yogurt lids with the centers cut out, and so on. For a giant bubblemaker, cut off the top and bottom of a large metal can with a can opener and hammer the inside edges until they are smooth (a parent's job). Dip either end in the solution and wave through the air. For more fun, try these additional bubble-making techniques.
