Many molecules are long, "braided" or "chained" groups of atoms. This is particularly true of polymers--which, by the way, is what many lanyards are made of (polyvinyl chloride, for example) and how they are made--the plastic ones are generally made by a type of braiding process, and the metal ones are generally a chain. Does that help?
I don't see how a lanyard is related to chemistry. This is because a lanyard is a rope or cord that is worn around the neck to carry an object. You should talk to your chemistry teacher about this; there might be a not-so-obvious connection.
