The Leidenfrost Effect is the scientific phenomenon in which water dropped on a hot surface floats on a cloud of its own vapor, seemingly slowing the evaporation process. <br /><br />When the hot surface is given a rigged, saw-tooth-like texture, the drops of water are propelled in fixed direction. <br /><br />Undergraduate students Carmen Cheng and Matthew Guy at the University Of Bath took this concept to the next level by creating a Leidenfrost Maze which motivates droplets of water to correctly traverse through a set puzzle of avenues. <br /><br />http://www.youtube.com/watch?feature=player_embedded&v=vPZ7sx3EwUY
