It’s our annual mailbag episode! We get a lot of wonderful reader emails suggesting topics for the show — and at the end of the year we try to answer some of them. This year, we’re tackling four fascinating questions. Why do grocery stores keep live lobsters in tanks, unlike any other animal? How did candy get rebranded as “fruit snacks” when fruit is already a snack? Whatever happened to perfumed ads in magazines? And what was the waterbed all about? We’ll get an answer from the waterbed’s inventor who still has four of them.

You’ll hear from Ray Shalhoub of Joray Fruit Rolls, consumer lawyer Steve Gardner, Jessica Murphy, aka the “Perfume Professor,” inventor Charlie Hall, restaurant historian Jan Whitaker, and the CEO of Crustacean Compassion, Dr. Ben Sturgeon.

This episode was produced by Max Freedman and Sofie Kodner. Decoder Ring is also produced by Willa Paskin, Evan Chung, and Katie Shepherd. Derek John is Executive Producer. Merritt Jacob is Senior Technical Director.

Disclosure in Podcast Description: A Bond Account is a self-directed brokerage account with Public Investing, member FINRA/SIPC. Deposits into this account are used to purchase 10 investment-grade and high-yield bonds. As of 9/26/24, the average, annualized yield to worst (YTW) across the Bond Account is greater than 6%. A bond’s yield is a function of its market price, which can fluctuate; therefore, a bond’s YTW is not “locked in” until the bond is purchased, and your yield at time of purchase may be different from the yield shown here. The “locked in” YTW is not guaranteed; you may receive less than the YTW of the bonds in the Bond Account if you sell any of the bonds before maturity or if the issuer defaults on the bond. Public Investing charges a markup on each bond trade. See our Fee Schedule. Bond Accounts are not recommendations of individual bonds or default allocations. The bonds in the Bond Account have not been selected based on your needs or risk profile. See https://public.com/disclosures/bond-account to learn more.
