What is the purpose of the balloon experiment?

What is the purpose of the balloon experiment?

The goal of the project is to demonstrate the power of gas procuded when of baking soda and vinegar are mixed. The goal is for the balloon to be blown up by the gas created.

What chemicals can inflate a balloon?

Baking soda is a base and vinegar is an acid. When the two materials mix, a chemical reaction occurs and the byproduct is carbon dioxide gas. It is the gas that causes the balloon to inflate.

How does baking soda and vinegar inflate a balloon?

Explain to your child that mixing vinegar and baking soda created a reaction — a gas, carbon dioxide. As the carbon dioxide fills the bottle, it then moves into the balloon to inflate it.

How does the baking soda and vinegar balloon experiment work?

So how does it work? The vinegar and the baking soda mix together to make an acid-base reaction. The reaction creates carbon dioxide gas that bubbles up from the mixture. The gas expands up and out of the bottle and inflates the balloon.

What causes the balloon to inflate?

Warm air is less dense than cold. Since warm air takes up more space than the same amount of cold air it makes the balloon inflate.

In what direction does the balloon expand?

Under normal, atmospheric pressure, the air on the other side of the surface pushed back and balances the forces, keeping the balloon from expanding. If you reduce the pressure on the outside, the air pushing against the inside will expands it outward. The less pressure, the more it expands.

What causes balloon to inflate?

How do you make a balloon experiment?


  1. Using a funnel, pour about a third of a cup of vinegar into the bottle.
  2. Then insert another funnel into the mouth of the balloon.
  3. Place two teaspoons of baking soda into the funnel so it falls into the balloon.
  4. Next, secure the the mouth of the balloon over the top of the bottle.

How do you inflate a balloon with vinegar?

Use the funnel to pour vinegar into the water bottle, filling about ⅓ of the bottle. Cover the top of the bottle with the bottom of the balloon. When ready, lift the balloon and let the ARM & HAMMER Baking Soda fall into the vinegar. Watch as the mixture fizzes, bubbles, and inflates your balloon!

Why does the balloon inflate in hot water?

Putting the bottle in hot water causes the air molecules inside to heat up and begin taking up more space (thermal expansion), causing air to enter the balloon and inflate it. When you move the bottle into the cold water, the air molecules cool back down and take up less space (thermal contraction).

What happens when a balloon is inflated?

Gas particles exert pressure on the walls of the container in which the gas is filled. For example, when a balloon is inflated, the air inside it expands, thereby exerting pressure on the balloon walls. As a result, the size of the balloon increases.

How do you make a self inflating balloon experiment?

Doing the Self-Inflating Balloon Science Experiment. Heat some water on the stove or in a microwave. If you don’t have access to something to heat water in the classroom, you can always switch out the hot water for yeast and sugar. Fill one bottle with 5 tablespoons of hot water. Add the “water” balloon to the top.

How do you inflate a water balloon with baking soda and vinegar?

Add 5 tablespoons of vinegar to the third bottle. Drop in two tablespoons of baking soda and quickly add the “baking soda” balloon. Stand back and watch. In our experiment, the water balloon didn’t inflate much at all. The hot air was not pressurized enough to inflate the balloon.

Why didn’t the water in the bottle inflate the balloon?

The heat rising from the hot water was not strong enough to inflate our balloon. However, hotter water or perhaps more water in the bottle might have done the trick. Want science planned for you ALL YEAR LONG?!

What can I use to inflate a balloon with yeast?

Clear plastic or glass bottle with a narrow neck (a water bottle or soda bottle work great) Inflating a balloon with yeast is a wonderful experiment to do with preschool and kindergarten aged children because all of the materials are nontoxic.
