Don't leave this in your pocket for 28 years!

Candies like Starburst are made mainly from corn syrup, which doesn't crystalize. It's also hygroscopic, which means it absorbs water from the atmosphere. Because the sugars in the corn syrup aren't locked together in a crystalline structure, they dissolve easily when water is added. The water starts dissolving the corn syrup and creates a sticky syrup, which leaks out of the wrapper.

So if you're going to leave something in a jacket for 28 years--such as the pocket of your high school letterman jacket--make sure it's made from solid sugar. Mint Lifesavers have a stable crystalline structure and will last!
