I got it the same way Jeff did. I tried it a million different ways, before and after I knew it, and nothing worked. I just couldn't get the height/distance needed out of the spring with it placed any closer to the starting point.
But, never say never...there probably is a different way, but using the one half-pipe and the right nudge where they are in the solution seems to be the only way to get the ball anywhere close to the target.
