Spanish marketing agency Momentum has installed 18 smart vending machines around the country that adjust the price of beverages depending on how hot it is.
Discovery News reports on the pricing structure:
"Up to 77 degrees Fahrenheit and the price is 2 euros or about $2.45. From 78 degrees F to slightly above 84, the price lowers to about 1.4 euros or $1.70. Anything over 86 degrees F and the drinks are 1 euro or $1.22. Special software allows the machine to automatically adjust."
The vending machines, which sell a lemonade product, were installed in water parks and amusements parks. And prices will remain temperature dependent through September.
