For anyone who has been to a music festival, a big gig - or even just a loaded bar full of thirsty punters, there's an invention that will make your life easier... and possibly a little bit drunker.
It should also light up the dollar-signed eyes of bar owners everywhere.
It's an invention that has literally come from the ground up, and uses common-sense technology to fill a plastic beer glass from the bottom.
The technology is relatively simple - a plastic cup with a hole in the bottom is coupled with a magnetic disk that seals the hole after the weight of the fluid is pumped in.

Full: Within seconds the cups are filled perfectly with beer and the barmaid is able to pour some more
It not only regulates the flow of beer, claims the manufacturers, but does it faster than a regular pour, and apparently leaves a perfect head.
The Bottoms Up pouring machine is the brainchild of GrinOn industries, which has manufactured and marketed the cup/disc concept.
It prides itself on the fact that the machine pours a perfect beer in record time, and its website shows videos of laymen beer pourers dispensing up to more than 50 beers in one minute.
It's not yet ready for market - but should catch the eye of any vendor who likes the idea of pouring beer swiftly and consistently.
The GrinOn website, not content with the revolutionary bottom-up pouring technique, also crows about the advertising potential of the magnetic disc - saying that it could carry a logo or phrase that punters can take home.
