Bubble mix improves after sitting so make it the day before you go out to play. Make enough for many activities. Gently stir together:
A wire coat-hanger, straws, and plastic rings that hold a six-pack of soda all make good bubble blowing tools. Even your hands, thumb and forefingers joined together, dipped in the mixture can make huge bubbles.
Cut off the ends of a quart milk carton to make a square wand, or make a square wand from a hanger. Ask your child what shape its bubble will be. Dip one end into the mix and gently blow through the other. Watch her surprise as a round bubble emerges from this square device. Explain that bubbles are always round. They naturally pull into the shape with the smallest surface area—a sphere.
Pour bubble mix into several cups, adding a few drops of different food coloring to each. Blow a rainbow of bubbles into the air and have your child “catch” them on a white piece of paper and watch them pop.
