This morning, I discovered that a can of soda that had expired almost four years ago (July 1st 2019) had been leaking everywhere. It had never been opened, but the Carbonic, Citric and Phosphoric acid and soda can eventually make microscopic holes in aluminum. I decided to do a taste test to see what it would taste like after eating through metal for years. It smelled like soda, but it tasted like water. Surprisingly, it was nice and refreshing. I was hoping for something more exciting, but that would have been funny. Please like me!
