*Sample* | 1-Hour about Rubber [1400-1910 A.D.] – Discovery, Early Uses, Charles Goodyear, & Visit to a Rubber Plantation (Bonus Episode #22)

Calm History - true bedtime stories & trivia for relaxing or sleeping.

Enjoy this sample of my newest Bonus Episode. The full version (~1 Hour) is on the Calm History-Bonus & Archives Podcast for Silk+ Members. Summary: I took two prior episodes about rubber (Archive episode #1 & Bonus episode #15) removed their introductions, deleted any promos or ads, and stitched them together. Now you can enjoy a pure and extended episode about the history of rubber.
