Colours in Bubbles

  • The colors of a bubble depend on the thickness of the film
  • As the bubble film gets thinner, yellow and green are canceled out and then blue is cancelled out as the soap film gets thinner
  • If the bubble is blue or green the soap film is thicker
  • If the bubble is yellow the soap film is thinner

Fun Facts

  • Bubbles will meet at the center, always at

an angle of 120 degrees

  • In the vacuum of space, a bubble wouldn't be able to form due to the lack of exterior air pressure to counteract the pressure from within
  • Pictures of bubbles are found in Western Europe as early as the 1500s
  • The first global financial bubble in stock prices occurred 1720 in Paris, London and the Netherlands.

Sizes, Shapes, and Forms

  • Tension in the bubble skin shrinks to the smallest possible shape for the volume of air it contains
  • A sphere has the smallest surface area so therefore a bubble no matter what the shape of the bubble wand is a sphere

What is a bubble?

  • A bubble is air trapped in soap film
  • Inside the soap film there is a thin layer of water
  • It's kind of like a bubble hamburger with soap molecule for bread and water molecule for meat

Introduction

Hello, Today I'm going to explain a

concept that nobody really thinks

about, bubbles. They're so fun and interesting but nobody really knows

why, how or what they are. And that's exactly what I'm about to explain.
