It seems silly to buy bubbles again and again when they are so easy to make. I've found that once you have a good bubble container with the special wand, they refill fantastically with this recipie. And if you don't have that wand, use a craft chenille made into the wand shape thoroughly soaked in the mixture!

Ingredients:
2 cups water
1/4 cup dish soap (not Ivory)
1-2 tablespoons glycerine

Directions:
Combine ingredients in a bottle (an empty bubble container is ideal)
