Homemade bubble blowing liquid. Great Summertime Craft.
Mix together gently:
4 cups water
12 teaspoons glycerine
8 teaspoons liquid tincture of green soap (available from drugstore but as a substitute, grate or grind very pure toilet soap and use 8 teaspoons of the resulting powder)
Let liquid stand for 24 hours before using.
