What is inside of a bubble, and why are they always round? To find out, let's get into some bubble trouble!
In this Saturday Science experiment, your young scientists will practice making predictions and using observations skills while playing with bubbles!
Materials
- 3 cups warm water
- 1 cup dish soap
- ½ corn syrup
- Shallow container
- 2 straws
- 24 inches of yarn
Process
- Carefully mix the warm water, dish soap and corn syrup in a large bowl.
- Pour into a shallow container such as a cake pan.
- Build your big bubble maker by feeding the yarn through both straws and tieing the ends together to make a loop.
- Spread the straws apart and dip the bubble maker into the bubble solution and make bubbles!
- Try to predict what shape each bubble will be and experiment with the placement of the straws and how quickly you need to pull the bubble maker out of the bubble solution.
Summary
Did you notice any patterns in the size and shape of your bubbles, or did the bubbles always turn into spheres?
Bubbles are created when air gets trapped inside a thin film of soap and water. As the bubble solution pulls inward and the air inside the bubble pushes outward, a round shape is formed. But, only for a short time. When the water in the bubble solution evaporates, the soap can no longer hold its shape, and the bubble will burst. POP!
