Answer:
That means “low pressure.” The air pressure outside the bottle is higher, so it actually tries to push into the bottle through the bottom hole. In doing so, it keeps the water in! When you release the hole on the top, there is no vacuum, so the water is free to flow out the hole into your sink.
