Summary

This episode of Version History explores the bizarre legacy of the Clapper, a 1980s device that turned lights on and off via sound. Host David Pierce and guests V Song and Alison Marsh discuss its origins, marketing by Chia Pet creator Joseph P. Dot, and its notorious unreliability. They cover lawsuits over false triggers, the ironic "Clapper Plus" remote, and why the clapping mechanism remains a cultural icon despite its technical flaws.
