Exploratorium Bubble Formula from the Exploratorium web site 2/3 cup Joy dishwashing soap 1 gallon water 2 to 3 tablespoons of glycerin (available in pharmacies or chemical supply houses)
Cyndi's Bubble Recipes from the Nathan's Wish web site 1/2 cup of dishwashing liquid (Dawn or Joy) 2 cups of water 2 teaspoons of sugar
What role does glycerin or sugar play in bubble formula? Are sugar or glycerin better than each other in some way w.r.t this formula?
