An introduction to Tube Food. Extremely difficult to acquire, at only 28,000 produced annually. We check out Caffeinated Apple Pie, Polenta with Cheese & Bacon, and Beef Stew. There are 19 different menu options in total. Produced for over 50 years now, and has been optimized for palatability and efficiency. Not mentioned in the video, Tube Food is stored in refrigeration, lengthening the shelf life well past the standard 3 years if stored at 80 degrees Fahrenheit, or 26.67 degrees Celsius.
