# What is inflating balloon experiment?

## What is inflating balloon experiment?

When baking soda and vinegar are mixed together, it creates a gas called carbon dioxide. The gas begins to expand in the bottle and starts to inflate the balloon. The more gas that is created, the larger the balloon will inflate.

## What experiments can you do with a balloon?

20 Balloon Experiments to Make Your Lessons Really Pop

• Blow up a balloon… without blowing.
• Design a balloon-powered car.
• Skewer a balloon without popping it.
• Float a balloon-powered boat.
• Create ice crystal explosions.
• Explore the science of swim bladders.
• Assemble a heart pump model.
• Learn how lungs work.

Can a balloon self inflate?

This reaction between the two causes a gas called carbon dioxide to bubble and foam. This gas having nowhere else to go, expands the balloon making the self-inflating balloon happen.

### What is inside a self-inflating balloon?

This self-inflating balloon has three components to make it inflate– citric acid, distilled water, and sodium bicarbonate (baking soda). The citric acid and distilled water are stored together in a small pouch inside of the balloon and the baking soda is stored outside of the bag.

### Will the balloon size grow bigger if more vinegar is in the bottle?

Both changes occur because new substances are created during the chemical reaction. The size of the balloon gives an estimate of the amount of gas produced in the reaction. If you want a bigger balloon you should use more baking soda and vinegar because then more carbon dioxide gas will be produced.

#### Can a balloon be used to model the expanding a universe?

This experiment modeled the expansion of the universe. As the balloon was inflated, the dots moved farther away from the home dot and each other. The results show that the farther away a dot is from the home dot, the faster its movement. Hubble concluded that the Universe must be expanding, like our balloon did.

#### Can yeast and water inflate a balloon?

For yeast to be active, it needs to be warm and moist. That’s why we added lukewarm water and placed the bottle in more warm water. As the yeast continued to react, it converted more and more sugar into carbon dioxide gas. This gas was trapped in the balloon, making it inflate as if by magic!
