BIZARRE WATER BEHAVIOR - SUPER HIGH TEMPERATURE MAKES WATER DROPLETS TRAVEL UPHILL

 
The Leidenfrost Effect  causes the water to levitate on the evaporated gas vapor.
 
 
If you've ever spilt water on a hot pan, you've seen the Leidenfrost Effect in action. 
 
The skittering and fizzing that takes place happens because the surface is super-hot, about twice as hot as the liquid's boiling point. 
 
This causes the water to levitate on the evaporated gas vapor which acts as a barrier that keeps the droplet and the hot surface separated.

Movement can be changed by adjusting the surface texture and temperature.
