How do beers fill from the bottom

But how does this magical machine work? Obviously, the cups have holes, but how do they reseal? The plastic glasses have a floppy fridge-magnet inside, a circle which sticks itself to a corresponding donut-shape strip around the filling-hole.

Here's a birds-eye view, grabbed from a video on the product site. So, the Bottoms Up pumps are fast, can hook up to any keg and — provided you have the rest of your gear clean and properly adjusted - you won't waste beer via foam. But there is an obvious problem: waste of those glasses. The company says bars and other venues can also print their own ads onto the magnets, which creates another revenue stream because drinkers can take the magnets home as souveniers of their night out.

In addition to their commercial products, Bottoms Up also sells a line of dispensers for home use. But those perfectly poured beers will cost you. Bottoms Up. Stories you might enjoy. There's a lot more alcohol in beer in Australia and in Europe. No offense to my fellow American beer-drinkers.

And the cost of a Bottoms Up plastic cup varies between US 36 cents and US 75 cents, depending on what size cup you want. But, according to Springer, the magnet that is attached to the bottom of the cup can also be used for advertising, "and so we have customers that actually make money by selling the advertising space on the bottom of the cup before they sell a beer", he said.

Springer, who says he's "loved beer since way before" he was supposed to, said that ever since he published a video demonstrating the invention on the video-sharing website YouTube two months ago, which has had over three million views, he had received "an enquiry from almost every country".

One of the major benefits of filling a cup from the bottom up, Springer said, was that you didn't have to "rely on the operator to know how to pour a beer". The idea to fill beers from the bottom up came to Springer at his dad's birthday party three years ago, he said. He then began daydreaming and stood up at the table "and stopped everybody's conversation" to tell them what he thought "would be cool" — a beer being filled from the bottom up.

Springer's dad told him that it "would be cool" but that he didn't think he could make it happen. The next day he thought of a name for the invention — Bottoms Up — and said that he then felt that he had to create it then as he had the perfect name.
