What causes plastic mush meltdown ?

[Nanna]

Thank you all for the replies.

I too can recall tackle boxes with melted stuff too. As far as the wacky rig, I had know about it in theory, it never dawned on me that the o ring would help make the plastic last longer. I have a few that I love, and have had for a while. i can't recall where they came from...I am always trying to keep them.

I've always thought those plastic worms and other artificials were full of cancer causing agents. I use live bait on most of my fishing trips, occasionally using Mr. Twisters during the spring when I'm chasing crappie.

NEVER put those things in your mouth and I've got a five year old boy I won't let touch those artificial baits.
