Molson Canadian knows how to make an interesting Beer Fridge. While most would simply give the high tech illusion Molson Canadian has actually went to great lengths to allow the tech in the fridge to actually work the magic. In all cases the goal is to unlock the fridge to enjoy some cold beer. The methods to open the fridge has changed from version to version. There is one that looks for an inserted passport and opens the fridge when a Canadian passport has been inserted, one that opens when you sing a correct version of O-Canada and one that opens after 6 people say I am Canadian in 6 different languages. Nice thing is that Molson has made some behind the scenes videos that show us how the tech works behind the scenes. Of course all the tech could be tossed out if they went the simple route by having a remote human in the loop monitoring the interaction but it is nice that they stayed true to the concept in each case.
