Yeast Sugar Add Water Attach balloon

PowerPoint Presentation:

By mixing the ingredients, the yeast metabolises the sugar, and expands. This metabolising releases the gas carbon dioxide. As the amount of gas increase, the sealed bottle forces it upwards, into the balloon.

As the air rises into the balloon, the volume inside the balloon increases. The stretchable rubber expands, resulting in the balloon inflating.
