Water Droplet Maze

Have you seen this water droplet maze?  The specific scientific reason that causes it to function is the “Leidenfrost effect”.   I’d never heard of it before seeing this video, but it is interesting. Once a surface temperature gets above 200 C, the water vapor beneath the water drop causes the water droplet  to float above the surface like a hovercraft.  So it appears that water does in fact run up hill (under specific conditions).  I think that this certainly has to have some useful applications.  Check it out!
