Watch what happens when a "magical" piano plays songs in real-time as commuters walk by in Chicago's Union Station. YouTube user Rob Bliss, who is the founder of RobBlissCreative, partnered with Amtrak to pull off this stunt to bring some holiday cheer to all the commuters who pass through Chicago Union Station.

 

A real pianist was hired to play tunes from a hidden room and interact with people that walked by.

 

Most of the commuters appear to be impressed by the piano playing, including a musician who stops to play along with it. The video was posted on December 11, has gone viral and has over 3 million page views.

 

Although parts of this clip appear to be staged, the reactions of the people involved will still bring a smile to your face this holiday season.
