Inside a Soap Bubble
Open to everyone until Friday, October 2
To keep it, print it while it is open.
A soap bubble is a pocket of air wrapped in a very thin film. The film is mostly water, held together by soap molecules.
In the picture
- Hollow air inside the bubble: the air pocket trapped by the film
- Thin water layer: the watery part of the bubble film
- Soap molecule row: round heads in the water and wavy tails in the air
Examples
- Blowing bubbles with a wand
- Foam on dish soap
Key takeaways
- The bubble film has water in the middle and soap molecules on both sides.
- The air inside is separated from the outside air by the thin film.
