Yeast and balloon experiment
All you need are a few simple materials to try this science experiment:
- 1-2 clean, empty water bottles (16 oz. or smaller
- 1 packet of active dry yeast
- 1 teaspoon of sugar
- 1-2 balloon
Blow up a balloon with yeast
Fill the the empty bottle with about one inch of warm water. Add all of the yeast packet and gently swirl the bottle a few seconds. When yeast is cold or dry the micro organisms are resting. By adding warm water the yeast dissolves, it becomes active – it comes to life! Don’t bother looking for movement, yeast is a microscopic fungus organism.
Add the sugar and swirl it around some more. Like people, yeast needs energy (food) to be active, so we will give it sugar.
yeast sugar balloon experiment
Blow up the balloon and release a few times to stretch it out then place the empty balloon over the neck of the bottle. The yeast is beginning to consume “eat” the sugar energy.
yeast and sugar balloon experiment
Let the bottle sit in a warm place for about 20 minutes and observe what happens.
What does Yeast do Explanation
As the yeast feeds on the sugar, it bubble, grows, and expands. It also produces a gas called carbon dioxide. With no place to go but up, this gas slowly fills the balloon. A very similar process happens as bread rises. Carbon dioxide from yeast fills thousands of balloonlike bubbles in the dough.
Fill out your worksheet as you begin, watch the experiment, and draw conclusions to teach kids about the scientific method and record your findings.
Try this experiment as explained above AND another one without the sugar. Ask the kid what they think will be different as a result.

Inflate a Balloon with Yeast Experiment
Did you know that you can inflate a balloon WITHOUT blowing air into it? It’s true.
In this simple experiment , young scientists use yeast to magically inflate a balloon. How cool is that?!
Check out the simple step-by-step below and then snag our 30 Science Experiments that are kid-approved!
Getting Ready
We headed into the kitchen to grab all of our supplies for this science experiment:
- Clear plastic or glass bottle with a narrow neck (a water bottle or soda bottle work great)
- 2 Tablespoons dry yeast
- 1 Tablespoon sugar
- 2-3 Tablespoons lukewarm water
- Party balloon
- Bowl or mug full of lukewarm water
Inflating a balloon with yeast is a wonderful experiment to do with preschool and kindergarten aged children because all of the materials are nontoxic. It’s nice when the kids can help measure out ingredients without worrying about what they are touching.
My kids helped me measure the yeast, sugar, and warm water into a cup.
They stirred the ingredients and then used a funnel to pour the brown mixture into the bottle. We added a little bit more water to help the yeast mixture get through the neck of the funnel.
We quickly stretched a balloon over the mouth of the bottle.
After placing the bottle into a mug full of warm water, we sat back to observe.
Inflate a Balloon with Yeast
Almost immediately, we observed bubbles in the yeast mixture.
I explained to the kids that yeast is a microscopic fungus that converts sugar into carbon dioxide.
The bubbles they saw were tiny bubbles of carbon dioxide gas that the yeast was producing as it “ate” the sugar.
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.
We set our bottle of yeast on the table and watched it while we ate lunch and read books.
We checked in with our science experiment every 10 minutes or so to observe any changes. Every time we looked, we noticed that the balloon was getting bigger and bigger on top of the bottle! Why?
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!
It took about an hour for our balloon to reach its maximum size.
The yeast bubbled up into the bottle quite a bit before it stopped reacting and shrank down again. Simple science at its best.

Yeast-Air Balloons. The purpose of any leavener is to produce the gas that makes bread rise. Yeast does this by feeding on the sugars in flour, and expelling carbon dioxide in the process. While there are about 160 known species of yeast, Saccharomyces cerevisiae, commonly known as baker's yeast, is the one most often used in the kitchen.
2-3 Tablespoons lukewarm water. Party balloon. Bowl or mug full of lukewarm water.

It's nice when the kids can help measure out ingredients without worrying about what they are touching.
04 - Yeast. Kitchen Science. Yeast Experiment. You will need 2 empty bottle, 2 balloons, 2 Tbsp. each of. different types of sugar*, 1/4 oz of yeast for each sugar. you want to test (1/2 oz for two types), 1 marker, 1 spoon, and an optional funnel. Recap the bottle and shake, or simply swirl the. contents of the bottle until well mixed.
at 28cm and therefore within this balloon, the most energy was created. The mixture with the least yeast added (1 spatula), gave us the lowest result in terms of circumference, 12cm. With 2 spatulas of yeast added, we obtained a result of circumference at 14cm and with 3 spatulas of yeast added, the result adhered was a circumference of 20cm.
The grains in dry yeast consist of lumps of living yeast cells encapsulated by a shell of dead yeast cells and nutrient fluid. When these grains dissolve in water, the living yeast cells are released. Dry yeast has a longer shelf life than fresh yeast, but fresh yeast is considered by many to give a better result in the kitchen.
Place a 600 ml beaker or large jar in an overflow pan. Fill the container to the 4. very top with tap water. Completely submerge (push the balloon under the water and allow the water to spill over the sides and into the pan. Stop when your fingers touch the water. The water in the pan is the volume of your balloon.
Procedure. 1. Set up a test tube as a control with 3 grams of yeast, 3 grams of sugar and 5 mL of water. 2. Add the yeast and the sugar, and then place a balloon mostly over the opening with just enough room to add the water. 3. Add the water and quickly put the balloon all the way over the opening.
Also make sure that the balloon is directly on top of the opening to the flask and is not blocked. Stretch the balloon a few times before using it** 5. Keeping the above in mind, place the balloon over the top of the flask 6. Wait until end of block, measure balloon at widest point with string, then measure the length of the
living organisms using yeast as a model. It will also explore how humans use this biological knowledge in everyday life. Procedure: 1. Set up four test tubes in a test tube rack. 2. Label each tube with a number, 1-4. Test tubes 1 and 2 will both have yeast, sugar and water. Test tubes 3 and 4 will both have only yeast and water, with no sugar. 3.
1. What happens to the balloon during the reaction? Explain your answer. The balloon inflates as it fills with the gas produced during the reaction. As the gas cannot escape, it fills and expands the balloon. 2. Name the gas that is being produced. Carbon dioxide 3. Are the yeast cells respiring aerobically or anaerobically? Explain your answer.
- Pour 5 mL of yeast into a graduated cylinder and then into the balloon. - Add 25 mL of warm water into a graduate cylinder, and then slowly pour the water into the balloon. - Note the time on your lab chart. - Tie the end of the balloon into a knot & shake your balloon contents for 10 seconds to mix it up.
Packet of yeast. Teaspoon of sugar. Warm water. Baking soda. Vinegar. Marker. Ignite your child's curiosity with an electrifying science experiment! Brace yourself for an explosion of fun as they explore the wonders of leavening agents. With yeast and sugar, watch as balloons gradually inflate, revealing the captivating process of carbon ...
Prepare and label the water bottles for your experiment. Rinse each bottle thoroughly with water and remove any labels. Number each bottle 1-5 with the permanent marker. Add 2 tablespoons (tbsp.) of sugar to bottles 2-5. Do not add sugar to bottle #1 because it is the negative control.
Conclusion: The yeast respired in the presence of sugar and oxygen to give CO2 (carbon dioxide) and H2O (Water). The CO2 produced caused the balloon to inflate. Find out more! This chemical reaction is used in bread making. The carbon dioxide produces the holes in bread which allow it to rise. The breakdown of sugar gives us energy.
