Try it at home:
Big Bubbles: Inyokern put children inside the bubbles! Pour 2-3 inches of bubble mix into the bottom of a kiddie pool. Place a sturdy box or step in the center. Use a hula hoop as a bubble "wand" and draw the bubble up around your child. Voila!
Bubble Solution (I got the recipe from the Exploratorium):
1 gallon water
2/3 cup blue Dawn dish soap
2-3 tbsp glycerine (check in the pharmacy by stomach medicines)
For best results, shake together and let set for 1-2 weeks!
