Yeast is a one-celled fungi important for their ability to ferment carbohydrates in various substances. It is used in the beer brewing process, baking. Kept dry, it does not have the ability to grow / reproduce.
When put into something like water, it dissolves the particles which enables it to "grow".
This growing creates a foam, releasing carbon dioxide, which gives off a strange acidy smell - in this case Vinegar.
Mixed with other things (for example beer brewing) it can smell like rotten eggs.
