What are bubbles?
Bubbles are created when an air pocket is trapped inside of film from a soapy sphere.
Why are they only spheres?
Even though many of the bubble wands are different shapes, bubbles can only form in a sphere because they are "minimal surface structures", which means that they shrink to the smallest shape they can be for the volume of air it holds.
Why do they pop?
Aside from landing on something pokey, they pop because the water between the soap films evaporates from the sun. That's why when it's colder, bubbles tend to last longer because of the slowed evaporation process and sometimes will freeze.
Why do bubbles stick together?
Bubbles want to have the smallest surface area it can possibly have, so it will share a common wall with another bubble. If there are three bubbles that join together, they will meet at the center at a 120 degree angle!
Where do bubbles get their colors?
Bubbles get their colors from light waves reflecting between the soap film’s outer and inner surfaces. The distance between the layers gets smaller as the water evaporates, making the colors change.
