McDonald’s partnered with JCDecaux in the Netherlands to create a very rewarding billboard. The billboard was outfitted with a weather detection monitor and a motorized door that would open the billboard casing once the environment got too hot. When the temperature reached 38.7 degrees celsius, the billboard would come to live and open up to allow the patient people to grab a free cup that could be redeemed at a local McDonald’s for a free McFlurry.
Each cup contained a special flavor. Thankfully it appears that everyone only takes one cup!
