Kids Science Experiments - Bubbles
Surface Tension
Bubbles
Materials you will need:
•Bottle of bubbles
•Bubble blowers(or simply make your own bubble solution).
Steps:
1. Dip the bubble blower or wand into your bubble solution.
2. Take it out slowly and blow in the center of the film of bubble solution.
3. Watch how the bubble forms into an enclosed bubble.
What makes bubbles round?
When air is blown inside a bubble it is pushed outwards in all directions. This causes bubbles to become round. Bubbles are made up of a thin film or skin of soapy water.
This thin film/skin that holds the air inside of a bubble is stretchy and when the bubble is stretched; it pulls tightly. This type of pull is called surface tension.
