36-Year-Old Twinkie is Still Intact

The longevity of Twinkies has been proven thanks to science teacher, Roger Bennatti. Back in 1976, the class had decided to test just how long the cream-filled snack would last. The 36-Year-Old Twinkie sat beside Bennatti's desk until his retirement in 2004; he then left it to the school encased in a glass box, where it remains on display in the principal's office.

Of course, it's no secret Twinkies are chocked full of preservatives, the pastry even contains beef fat.
