Scientific question

We did this experiment in science and were curious about the results:
In this experiment, we inflated a balloon using vinegar and baking soda. Then we left it to see what would happen. After a few days the balloon deflated and then got sucked into the bottle (see above). We want to know why this happened? (Anselm is calling it "exflation")

    Vinegar is an acid and when it is put in contact with baking soda a reaction happens. In this reaction Carbon Dioxide (CO2) is produced. CO2 is a gas and it causes the ballon to inflate.

    After a few days most of the gas will leak out and the rest will settle back into the jar because CO2 is heavier than air and is pulled down by gravity.

    I like the term "exflation".

    Hope that helps.
