Bubble Solution Formula for Enrico

My son Enrico loves soap bubbles, this is the formula I use for big bubbles:

  1. 2/3 cup Dawn liquid diswashing detergent
  2. add water to make a gallon
  3. add 1 tablespoon of glycerine (glycerol)
The solution becomes better with age, leave it in a open container for at least one day before use.
