Episode Description

Deep Freeze

Take a look at the technology of cold. Think your home freezer is "cool"? Try spending some time in a 12-story unit filled with 135 million pounds of ice cream. Enter Arctic vaults that store millions of different seeds and learn how scientists have mastered temperatures of -200 degrees F and below. Explore how the cold not only preserves and chills, but also shatters rubber tires, strengthens steel, and fuels rockets. Finally, visit Alcor, where researchers keep cadavers on ice in hopes of future revival.
