Free McDonald’s McFlurry outdoor heat activated billboard

When a heatwave hit the Netherlands earlier this month, McDonald’s conjured up a novel way to keep people cool. The fast food chain partnered with outdoor advertising company JCDecaux to create a heat-activated billboard. When the temperate hit a record 38.6 degrees Celsius, a panel opened automatically to offer out 100 McFlurry cups to passing pedestrians, they were directed to collect their free ice cream at the nearby McDonald’s store.
