Sip-and-puff or sip 'n' puff (SNP) is assistive technology used to send signals to a device using air pressure by "sipping" (inhaling) or "puffing" (exhaling) on a straw, tube or "wand." It is primarily used by ...
Unlike the rubber bulb dispenser which primarily moved air with a small amount of fluid, modern spray bottles use a positive displacement pump that acts directly on the fluid. The pump draws liquid up a siphon tube from the bottom of the bottle and forces it through a nozzle .
A drinking straw is a utensil that uses suction to carry the contents of a beverage to one's mouth. A straw is used by placing one end in the mouth and the other in a beverage.
