Yeast Balloon Experiment

You have probably used yeast for baking homemade goodies, but have you ever tried to use it to inflate a balloon!?

That's right! This cool science experiment will show you how to use yeast, water, and sugar to blow up a balloon!

This is one that your kids will love doing over and over again, and it's super simple and easy to do at home too.

The science behind this yeast balloon experiment:

The reason yeast blows up a balloon is the same reason yeast is used in many bread, dough, and baking recipes!

Yeast is a single-celled organism described as a “sugar-eating fungus”. Yeast needs food, warmth, and moisture to thrive and grow.

As the yeast grows and converts the sugar into energy, it releases Carbon Dioxide gas in a process called fermentation.

The tiny little carbon dioxide (CO2) gas bubbles get trapped in bread dough as it bakes and is what makes bread so soft and spongy!

Now in our experiment, the warm water in the bottle provides warmth and moisture for the yeast, while the sugar provides the food for the yeast to grow and expand.

The addition of carbon dioxide in the bottle increases the air pressure in the bottle, which pushes air into the balloon and inflates it!
