Yeast Fermentation Experiment

Postby sept23 » Sat Dec 06, 2008 2:32 am

When you put yeasts into a flask with apple juice and cover it with a balloon. Suppose that the yeast would go through anaerobic respiration to produce carbon dioxide, which causes the balloon to expand. Instead, the balloon in my experiment not only deflated, but it also got sucked into the flask. Can anybody explain to me what is it that cause the balloon to deflate and pulled into the flask?
