Worms & Worm Wheels - A Primer

First published in 1973, the novel How to Eat Fried Worms by Thomas Rockwell tells the story of Billy and his desire to win a bet by eating a worm a day for 15 days. Although the thought of eating worms is not something most of us would consider doing, Billy finds a way to ingest a nightcrawler each day. Much like this children’s story, most mechanical engineers know about worms, but are not comfortable designing them into their systems.
