B is for bubbles

I love them big and small. They do the same thing. They float softly in the air until something magically pops them...pretty!

Bubbles are films of a solution stretched around some kind of fluid, usually air. The film that is easiest to make is a soap (or detergent) in water
solution. The film has thickness and an inside and an outside. Soap and detergent molecules are long thin molecules with many hydrogen atoms that
attract each other. They have an electrically charged end that is attracted to water. The soap bubble surfaces have the soap or detergent molecules arranged so that they line up side by side. In the middle of the film is a water and soap solution.
