Ever play with a slinky? If you line it up right they will "walk" down the stairs. Here's a waterfall that .. well... walks down the stairs.

It's a water slinky! Waves make their way down a huge flight of stairs during a light rain. Let me know if you've ever seen anything like it!

Science or black magic I leave it to you to decide.

By the way this is far more relaxing and less gross than the sink video.
