Ernest Shackleton's Whiskey
Ernest Shakleton was a famous explorer of the Heroic Age of Antarctic Exploration who was on the Endurance and an explorer of the South Pole. Above is a video from the Lede (NYTimes) showing how explorers just found some of his whiskey 101 years after he left it in the South Pole. If not appropriate for your class, it is certainly very interesting as a short video.
