"Nettet30. aug. 2012 · "It’s easy to create one of these twistless springs with a telephone cord," says Gerbode, "and they’re annoying. But with the phone cord, you can pull on both ends and it will straighten out into a flat ribbon. What’s strange about the cucumber tendril is that if you pull on the ends, it actually overwinds, adding more turns to both helices." " - How the cucumber tendril coils and overwinds
