Description
The ‘Soap Bubble Ring’ demonstrates the principles of surface tension and the laws of fluid dynamics.
When you lift the iron ring dipped in soapy water, you create a giant soap bubble around yourself. This happens because the soap solution forms a film over the ring, which, due to surface tension, tries to keep the surface as small as possible.
The principle of surface tension, the force with which molecules attract each other, finds broad application in industry and science. For example, in the development of water-repellent materials and coatings. In the future, based on this principle, self-cleaning materials could be developed. This means that a solar panel, for instance, wouldn’t need to be cleaned anymore, ensuring it always delivers the maximum amount of energy.
How do you make a soap bubble you can stand in?
- Stand in the middle of the circle.
- Lift the ring.
- Create a soap bubble you can stand in.
