Soap Bubble Burst

Soap Bubble Burst
soap bubble is a very thin film of soapy water that forms a sphere with aniridescent surface. Soap bubbles usually last for only a few moments before bursting, either on their own or on contact with another object. They are often used for children's enjoyment, but their usage in artistic performances shows that they can also be fascinating for adults.

The perfect soap film for bubbles comes from the perfect solution. Numerous variations of soap bubble solutions appear on the Internet. Almost all recipes involve liquid detergents, such as Joy or Dawn, and water. Unlike soaps, detergents don't contain a carboxylate group that reacts with calcium and magnesium ions found in hard water to produce a scum. Therefore, detergents aren't dependent on distilled water for bubble formation.

How To Make Colored Soap Bubbles
  1. If you are making your own bubble solution, mix the detergent and water.
  2. Add the sodium hydroxide and indicator to the bubble solution. You want enough indicator so that the bubbles will be deeply colored. For each liter of bubble solution (4 cups) this is about 1-1/2 to 2 teaspoons of phenolphthalein (red) or thymolphthalein (blue).
  3. Add sodium hydroxide until you get the indicator to change from colorless to colored (about half a teaspoon should do the trick). A little more sodium hydroxide will result in a bubble that stays colored longer. If you add too much, the color of the bubble won't disappear when exposed to air or rubbed, though you can still react it with club soda.
  4. You may find it necessary to dissolve the indicator in a small amount of alcohol before mixing it with the bubble solution. You can use pre-made indicator solution, adding the sodium hydroxide to the indicator rather than diluting with water.
  5. You've essentially made disappearing ink bubbles. When the bubble lands, you can make the color vanish by either rubbing the spot (reacting the liquid with air) or by adding a little club soda. Fun!
  6. If you have disappearing ink, you could mix it with bubble solution to make disappearing ink bubbles.
