Blow A Bubble Inside A Bubble Cool Science Experiment
In this cool and easy science experiment, we’re going to explore and investigate bubbles by blowing a bubble inside another bubble.
Materials:
- Water
- Sugar
- Liquid dish soap
- Pipette
- Scissors
Instructions:
- Add a tablespoon of sugar to one cup of warm water.
- Mix until the sugar is dissolved.
- Add two tablespoons of liquid dish soap to the sugar and water solution. Mix gently to avoid creating bubbles or foam.
- For the best results, allow the solution to sit overnight.
- Snip the end off of the bulb of the pipette.
- Find a very smooth and flat surface.
- Dip the end of the pipette into the soap solution.
- Hold the end of the pipette near the flat surface and slowly blow a bubble. Pull the pipette away from the surface as you blow to allow the bubble room to grow.
- Once you have a decent sized bubble, stop blowing and remove the pipette.
- Dip the pipette into more of the soap solution.
- Now gently push the pipette through the bubble and blow a new bubble inside the bigger bubble.
- Keep repeating and see how many bubbles you can get inside of the main bubble.

How it Works:
When you blow a bubble inside a bubble, this actually forces the outside bubble to stretch to have to accommodate the additional air volume. The outside bubble is elastic and is able to stretch, thus allowing another bubble to be blown inside. The sugar will help slow evaporation and allow the bubble to last longer.
Make This A Science Project:
Add more soap. Try different brands of liquid dish soap. Try different types of soap.
