What's the Stuff Between the Wafers of a Kit Kat?

If you've ever eaten a chocolate bar, you've probably eaten a Kit Kat. The four-fingered bar is one of the world's most popular treats and in 2014 was named the "most influential" candy bar of all time by TIME Magazine. Over the years, Kit Kats have been produced in over 200 flavors, from the standard milk chocolate to Japanese-created oddities like ginger ale, soy sauce and sake. The candy even had a version of the Android operating system (v4.4) named after it.

But no matter how familiar you are with Kit Kats, there's something about the filling that you might have wondered about. In between the layers of wafer, there's a different type of chocolate. It's lighter in color, and has a much softer, more crumbly texture than the hard chocolate on the outside. That's because it's not actually chocolate; it's mashed up Kit Kats.

You see, not every chocolate bar is created perfectly. When they roll off the production line, quality assurance technicians remove the Kit Kats that have too many exterior air bubbles, off-center wafers, or any other imperfections, right down to those that simply aren't shiny enough. As far as the manufacturers are concerned, consumers don't want imperfect chocolate bars. But rather than being thrown away, those second-class bars are recycled back into the production process.

After being ground up into a fine paste, they form the filling you find between the Kit Kat's wafers. In many ways, it's a stroke of genius—no edible Kit Kat is wasted!

'Lime Disease' Could Give You a Nasty Rash This Summer

A cold Corona or virgin margarita is best enjoyed by the pool, but watch where you’re squeezing those limes. As Slate illustrates in a new video, there’s a lesser-known “lime disease,” and it can give you a nasty skin rash if you’re not careful.

When lime juice comes into contact with your skin and is then exposed to UV rays, it can cause a chemical reaction that results in phytophotodermatitis. It looks a little like a poison ivy reaction or sun poisoning, and some of the symptoms include redness, blistering, and inflammation. It’s the same reaction caused by a corrosive sap on the giant hogweed, an invasive weed that’s spreading throughout the U.S.

"Lime disease" may sound random, but it’s a lot more common than you might think. Dermatologist Barry D. Goldman tells Slate he sees cases of the skin condition almost daily in the summer. Some people have even reported receiving second-degree burns as a result of the citric acid from lime juice. According to the Mayo Clinic, the chemical that causes phytophotodermatitis can also be found in wild parsnip, wild dill, wild parsley, buttercups, and other citrus fruits.

To play it safe, keep your limes confined to the great indoors or wash your hands with soap after handling the fruit. You can learn more about phytophotodermatitis by checking out Slate’s video below.
