Spanish marketing agency Momentum has installed 18 vending machines that offer discounts when the temperature rises outside.

The vending machines are filled with Coca-Cola's lemonade drink Limon&Nada. This creative method of pricing a product will last throughout the summer months. The machines are mostly located in water parks and other attractions in Spain.

MarketingNews.es reports that the temperature and product price is shown on an information screen. There are three different prices, each depending on how hot it is.

At temperatures of up to 77 degrees Fahrenheit, the cans of lemonade cost 2 euros. At 77.8-84.2 degrees, they are about 30% cheaper, at 1.40 euros. When the temperature reaches 86 degrees, they are half price at just 1 euro.
