Bubble, bubble, toil and trouble

bubble, originally uploaded by toyfoto.

Did you know bubbles are always spherical -- regardless of the shape of your bubble-making wand -- because they hold the gas inside of them with the least possible surface area? The geometric form with the least surface area for any given volume is always a sphere. The exception to this rule, of course, is when the bubble is surrounded by other bubbles. But when the other bubbles pop, the oddly shaped one returns to its spherical form.

Did you know regardless of how you color your bubble juice, the bubbles themselves will take on the color of the light that is refracted from them? Although you can't color a bubble with paint, you can paint with pigment-added bubbles by popping them on a piece of paper.

Do you know why bubbles pop? Dryness kills bubbles. When you make bubbles in the sun they even evaporate more quickly.

Did you know that if you wet your hands you can successfully catch bubbles? You can even penetrate your bubbles if you keep your tools wet.**

Did you know you can make your own bubble solution?
1 part diswashing liquid
15 parts water
.25 part white Karo syrup

To paint with bubbles add a few drops of food coloring or washable paint.

**Did that sound a little too racy? Science museums do that to me, I guess.
