Hi all,


What is different about plastic to make it worm-proof?


My dad is a plastics engineer, so I asked him. Seems many worms are made
with a certain "plastisol" (some kind of very low density plasticizer --
makes 'em wiggly), and this plastisol reacts poorly with styrene and some
higher density polyethylene plastics. If you put the worms directly in a
non-worm-proof container, the worms will melt the conatiner.

I just keep my plastics in the little baggie they came in, and then in a
binder to keep them together.
