This ingenious interactive ad for Swedish pharmacy brand Apotek is just perfect. When the train pulls into the station it feels exactly what you feel: the wind blowing through your hair.

As the video above explains, the advertisement for a new line of hair products is outfitted with audio sensors so when the train comes roaring into the station, the perfectly coiffed model's hair gets all mussed up. What better way to make potential customers identify with your product than to show them that you feel their pain. [Mashable]
