World’s Oldest Twinkie Turns 40, Still Refuses to Decompose

In 1976, Roger Bennatti, a chemistry teacher at George Stevens Academy, in Maine, unwrapped a fresh Twinkie and placed it atop a classroom chalkboard so he and his students could see how long it took for it to decompose. 40 years later, that question remains unanswered, because mould simply refuses to grow on the world’s oldest Twinkie.

The official shelf-life of a Twinkie – as stated by the company making them nowadays – is only 25 days, but as the famous Twinkie of George Stevens Academy clearly shows, it’s really a lot longer than that. It has been sitting in a glass case for four decades now, and even though it might not be safe to eat, it is looking fantastic for its age. Its shape hasn’t change a bit, and if mould hasn’t grown on it so far, chances are it never will.
