What is Air pump?
A '''air pump''' is a [[pump]] that is used to inflate things, like a [[basketball]]. The pump often has a [[needle]] at the end and can be used to inflate other objects as well. [[Bicycle]] tires are normally filled with air. With extensive use, the [[tires]] may lose air and need to be inflated. When the air gets moved, an area of low pressure gets created which fills up with more air.<ref>{{Cite web|title=Pump Theory - Principles|url=https://powerequipment.honda.com/pumps/pump-theory-1|access-date=2018-11-26|website=powerequipment.honda.com|archive-url=https://web.archive.org/web/20181126092801/https://powerequipment.honda.com/pumps/pump-theory-1|archive-date=26 November 2018|url-status=dead}}</ref> == References == <references /> {{tech-stub}} [[Category:Mechanics]] [[Category:Tools]]
