I suspect it may also reduce evaporation. The formula for blowing giant bubbles is water, Dawn detergent, and glycerine. The soap lowers the surface tension of the water allowing the water molecules to let go of each other easier and form bubble instead of drops. The glycerine, which would increase surface tension, seems counter intuitive. Evaporation (and sharp objects) are a giant bubble's natural enemies. The small dose of glycerine helps reduce evaporation. Perhaps worth a try? I would suggest a 20% glycerine solution as a starting point.
