Piano Stairs Make Music
Given the choice of taking the escalators or the stairs, here’s some advice, take the stairs, particularly if you find yourself at Wulin Plaza in Hangzhou, China. Just last week they installed stairs that resemble black and white piano keys. When walked upon, the steps produce relevant musical note sounds, resulting in a truly melodic experience. In total there are 54 steps. You can watch a video of the stairs in action at the SINA English website.
