Warm weather is bubble season for kids who want some outdoor fun. Here’s an inexpensive homemade solution for blowing bubbles: Mix 1 tablespoon glycerin with 2 tablespoons powdered laundry detergent in 1 cup warm water. Any unpainted piece of metal wire can be turned into a bubble wand: Just shape one end of the wire into a circle. Blowing into the mixture with a straw will make smaller bubbles float into the air. For colored bubbles, add food coloring.
