Q. Dear Twig: What's a nurdle?
A. Nothing. What's a nurdle with you?
Q. I'm thinking that isn't funny.
A. You're right. OK. This. Nurdle: a small, round plastic pellet the size and shape of a pea, more or less. If you take a pea, hold it in your hand, look at it closely, and imagine it's made out of plastic, that's a nurdle. Factories make them by the billions and billions. Ships and trucks haul them by the billions and billions. Other, different factories use them by the billions and billions to make plastic things. They melt and mold the nurdles into just about any sort of plastic thing you can think of: pens, yogurt cups, cell phone covers, toys involving large groups of small domestic animals, and so on.
A. So, I'm out of room. More next time!
P.S. "Plastic resin pellets" and "mermaid tears" (when littered in oceans) are other nurdle names.
Nurdles were mentioned just briefly last week when we talked about plastic pollution in the oceans (http://www.ag.ohio-state.edu/~news/story.php?id=5169).
