Bubbles occur naturally, so they have always been around, but the sport of playing with bubbles didn’t really exist before soap. The Pear Soap Company, in England, was responsible for the 19th century popularization of both soap and bubble blowing. Bubble toys were largely limited to bubble pipes until the middle of the 20th century.

Why do bubbles have color? Can I color bubbles?

We see the colors in a bubble through the reflection and the refraction of light waves off the inner and outer surfaces of the bubble wall. You can't color a bubble since its wall is only a few millionths of an inch thick. A bubble reflects color from its surroundings. As a bubble wall gets thinner, the bubble loses its color and can become nearly invisible.

Why are bubbles round?

Bubbles and balloons have a lot in common!  Scientists refer to them as  "minimal surface structures."  This means that they always hold the gas or liquid 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, not a pyramid or a cube or any other form.

Why do bubbles pop?

There are many reasons why a bubble pops. Evaporation of its water content, air turbulence, and, most commonly, dryness - contact with a dry surface or dry air. When you make bubbles in the sun, they evaporate quickly. When there is a strong wind, or even a gentle breeze, bubbles are much more difficult to create and are popped by the wind's force. If the air is very dry, as it is in the desert, or if a bubble touches a dry finger or a piece of clothing or the ground, it pops instantly. Here are some recommendations for the best conditions for making bubbles, especially giant bubbles:

 

Work in Shady areas

Try bubble making right after the sun sets.

Make bubbles when the air is still or only slightly breezy.

Play with bubbles after a rainstorm. 

Stay in open areas where your bubbles won't run into dry objects.

Keep your bubble tools really wet with bubble solution.
