Blowing bubbles can make anyone feel a rush of therapeutic leisure, whether you're an infant or have one foot in the grave. Call it the Glinda the Good Witch syndrome: The dainty, ethereal prisms make everything look magical.
Even better, they don't have to be reserved for a hot day in the backyard. Soap bubbles might very well blow the minds of your little ones on a snow day, too. While this experiment works best in very cold temps (we're talking close to zero degrees Fahrenheit or negative 18 degrees Celsius), you might also be able to get a cool result from temps in the 20s. You can make your own soap solution, or just buy the cheapo bottle-and-wand set made for kids. Start by heating the soapy water so it's warm or hot, then let the little ones blow bubbles outside. If you can catch one on your wand, watch it carefully: It will freeze into a delicate ball.
