Usually, the only math required at a bar is tip calculation. But a new algorithm-based program from Miami company Drink Exchange makes ordering cocktails much like playing the stock market.If a particular concoction is popular, the software automatically raises its price. Conversely, the less popular a drink, the less it costs. Bar promotions (such as a sudden “market crash,” when all prices fall) affect prices minute to minute. Television screens and LED tickers display the prices so patrons can follow along—and throw elbows to get their orders in.The system is currently set up in 25 watering holes, and there are plans to be in 300 by year’s end.

Seriously? Would you do this? I don’t want to work this hard just to get a drink.
