Why does yogurt explode when you open it?

Yogurt does not typically explode when you open it. However, if the yogurt has been contaminated with yeast or bacteria, it may produce gas that causes the container to bloat or even burst open. This can happen if the yogurt has not been properly refrigerated, or if it has been left open for an extended period. To avoid this, it is important to keep yogurt refrigerated and to consume it within a few days of opening.
