Last month, Science Diction received a letter from a listener named Ben. He wanted to know about ambergris, a strange substance that washes up on beaches from time to time.

So today, we’re talking about this thing that for centuries, rich people coveted, rubbed on their necks, and even ate, all without having any idea what it really was. If they had known, they might have put their forks right down.

Plus, Science Diction now has a phone number! If you, like Ben, want us to cover a certain word, you can call in, leave us a message, and we might play it on the show. Call 929-499-WORD or 929 499 9673. Or send us an email at podcasts@sciencefriday.com.
