1. Mix 10 percent liquid dishwashing detergent (Dawn or Joy are considered the best) by volume with 84 percent distilled water (available in grocery stores) and 6 percent glycerin (available in drugstores).
2. Stir. Do not shake or excess bubbles will be produced. Do not use low-sudsing detergent. If you get any suds on top, skim them off with your hand before using.
3. For very dry days, add 10%-50% more water.
4. Bubbles thrive in high humidity. On dry days it is still usually humid enough early in the morning.

Stuff to use to make bubbles: Coat hangers (bend into a circle), Tin Cans, Plastic Six-Pack Holder, Your Hands, A Funnel.
