Name of the substance on which water cannot stay?

There is a show on discovery, 'You have been warned.'. In that show, once I remember seeing an unusual substance, when, on water was poured in it, even on a perfectly straight (non-slanting) table, water just didn't stay on it. It "rushed" in random directions and then when it was not in contact of the substance, it stopped. I don't remember the episode, nor the substance. 


What could this substance be, or if they're a class of compounds, what are their properties?   

**Can anybody also point out that episode?**
