Trivia I just was reminded of:

^Trivia I just was reminded of: Vacuums (like a vacuum cleaner) don't SUCK anything. They create a NEGATIVE pressure (like sucking the air out of a straw for example), and the air and dirt along with it, gets PUSHED in. Common, everyday, vacuum cleaner. Space age technology. It's worth being amazed at everyday things.^
