Place the balloon over the mouth of the bottle and watch what happens over ~10 minutes. Why is this happening? The balloon deflates and begins to fall into the bottle. As the temperature of the air inside decreases, the air compresses, which decreases the volume of air. Take the balloon off and put the Snapple bottle (with the water still in it) in the freezer for an hour or so. Take it out and put the balloon over the mouth of the bottle again and watch

As the air inside warms up, the air molecules spread out, causing the volume of air to increase (although density decreases). Take the same bottle and balloon and place the balloon over the mouth of the bottle (so no air can get into our out of the bottle) and try to blow up the balloon. What happens? You can only blow it up to the point where the air pressure you’re creating inside the balloon equals the air pressure inside the bottle....
