National Twinkie Day is celebrated on April 6 every year.
What is a Twinkie you ask ?
A Twinkie is an American snack cake, described as "golden sponge cake with a creamy filling".
How Twinkies Work
You've probably heard the one about how Twinkies could survive a nuclear attack or the one about that secret ingredient, embalming fluid.
So, what are Twinkies, exactly?
Can they really sit in a store for 30 years?
Today's Twinkie has a much longer shelf life than the ones made in 1930, but not as long as some people think. A variety of myths and urban legends have sprung up around the Twinkie's longevity, claiming that it stays fresh for decades, would survive a nuclear war and that the company is still selling off the original batch made in 1930, still fresh almost 80 years later. In fact, a Twinkie's shelf life is officially 25 days.
