I can play slide a little, though I'm not good at it. Two things that make it a hundred times easier is to raise the action on the guitar (most players have a guitar set to the side with the action raised for playing slide on) and tune to an open tuning. If your not familiar with open tunings, it's basically tuning your guitar to a chord (open C would be tuning your guitar to where when you strum the guitar without any fingers on the fret's, your strumming a C chord.)
