Answer:
The model works in a similar way: When you pull down on the rubber, the space inside the bottle gets bigger and the air spreads out. You now have lower pressure inside the bottle, so the higher pressure outside pushes air in; the balloon is blocking the way, so it takes in the air. (This is like breathing in).
