Prison Experiment, The Real Noah's Ark, The Informant

At the Marin History Museum in San Rafael, California, a tattered and time-worn briefcase in the collection once belonged to an eccentric doctor who performed gruesome and controversial surgeries, all in the hopes to make the old young again. At the Wyatt Archaeological Museum in Cornersville TN, visitors can see a giant slab of rock unearthed from the hills of Turkey which some believe is fossilized proof of a biblical vessel. And stored deep within the archives of the FBI, a reel-to-reel tape recorder from the early 1990's was once wielded by an informant who helped expose a massive corporate conspiracy, damning himself in the process.For even more Mysteries at the Museum, head to discovery+.
