BUBBLES!

Some links to help you with your bubbles

• If you want an easy way to make bubble wands for your group, try this:
  1. Each wand will require four plastic straws and about 30 inches of string. A soft cotton string that absorbs water is best.
  2. thread two straws onto your length of string
  3. tightly tie the two ends of the string in a knot
  4. slide the straws so that you form a rectangle with the knot inside one straw
  5. now get your remaining two straws and poke each one into the end of one of your rectangle straws to form handles. (Push it in about an inch or so.)
• Why do math people like soap bubbles so much? Because they show us how minimal surfaces work! If it weren't for gravity, wind, and other imperfections, a soap bubble would find exactly the smallest possible surface area to span a given boundary. These are called isoperimetric problems and they are notoriously hard for humans to solve! So why is it that a bubble knows the answer?

• To get a really good bubble formula, you don't need glycerin; a bit of corn syrup will do.
• Here is another page with a bubble recipe, but the page is full of ads.
