Now, let's get a little sciency and talk about the chemistry behind candy corn. It turns out that the sugar in candy corn is what helps preserve it, by drawing out moisture and preventing the growth of bacteria and mold. But, if you introduce moisture into the equation, the sugar can start to break down, and your candy corn can become stale or even develop off-flavors.

So, how can you make your candy corn last longer? Well, for starters, you can store it in an airtight container, like a plastic bag or a glass jar. You can also add a few silica gel packets to absorb any moisture that might be present. And, if you're feeling extra adventurous, you can even try freezing your candy corn to keep it fresh for an even longer period.
