Why is it that when you put a small hole on a bottle that is close, the water inside doesn’t come out but if you open the bottle cap, the water goes out?
In: Physics
When water comes out of the bottle something needs to replace it, this is typically air. When you open a small hole at the bottom there is no chance for air to enter the bottle, if water came out then there would be a vacuum at the top of the bottle. When you remove the cap air can rush in and allow the water to fall out the bottom.
