McDonald’s Billboard With Heat-Sensitive Paneling Doles Out McFlurries in Super Hot Weather

Very cool outdoor

Heat-sick Dutchmen rejoice! McDonald's in the Netherlands teamed up with outdoor ad company JCDecaux to create a billboard with heat-sensitive paneling that contained 100 free McFlurry cups. When it gets too hot outside, the panel opens, and people can take a cup to redeem for a free McFlurry. David Kiefaber is a frequent contributor to Adweek's creativity blog, AdFreak.
