I'm going to have to disagree with you on the scent part Cow. It has been well studied and documented that the fishes sense of smell is extremely acute, and while they probably wouldn't know WHAT that smell is they would certainly know if it smelled unnatural to them.

As for the sound, people have been known to drift jigs instead of bobber them. So the sound that they make as they hit the rocks can either get their attention or spook them.

As for the wood chips...well, either he was a bit wickie in the whacky woo or there was something about that wood that turned him on. May have to bait up with balsa next time I'm out.
