Today our scientist showed us the magic powers of sugar and yeast and we had a quick chemistry lesson. When yeast is mixed with sugar in a liquid, the yeast (a living organism) becomes activated. It eats the sugar and essentially burps out carbon dioxide. It's a much slower reaction than we're used to with baking soda and vinegar, but it's neat to be able to watch it happen in slow motion. With the creation of carbon dioxide, the pressure in the bottle increases and the balloon fills. It's like watching bread rise! Check out the video below for the details.
