Leidenfrost Maze: scientists magically control water droplets

This video of a Leidenfrost Maze was created to showcase a bizarre phenomenon known as the ‘Leidenfrost effect’.  

Basically, when a liquid is heated past its boiling point, instead of boiling, it will become incased in a vapor layer that prevents it from boiling rapidly. And in this video, water droplets are moved through a maze by being placed in contact with an extremely hot aluminum surface with a saw-tooth texture. Amazing.
