Slippery When Wet?

Is it possible to create a surface that is slippery?

With that, is is possible to create a random variable to purposely make the player slip, as in force the player to fall down?

I want the player to have to cross a down tree as a bridge and just to be an ***; I want to force the player to fall every now and then, no matter how careful of a player they are.

Just fake it, get their current location and just push them a little bit left or right. I would use anim notifiers so that you can randomly do it when their foot hits the surface.
