Strange things you sometimes learn about physics, there really is no such thing as suction. The outside atmosphere is usually pushing in, in fact.
And there is a lot of air pressure on the surface of the earth. You just don't notice it because it is equal all around you.
But I have just one question: When you use a vacuum cleaner, are you pulling the dirt in? Or is the atmosphere pushing it in? Because that last one seems confusing to me.I know the vacuum cleaner does create a partial vacuum (hence the name).
But back to my question: Pushing? Or pulling?
