Skittles Fizzl'd Fruits

        Back in October I heard that Wrigley's was introducing some new Skittles. These weren't just new flavours, they were going to be a completely new way to experience the chewy fruit-flavoured candy lentils. Skittles Fizzl'd Fruits are billed as Fizzling fun for your mouth. As you can imagine from the name, they're Skittles with a foaming, fizzy component. The package is cobalt blue and holds the same amount as the Sour Skittles, 1.8 ounces (the regular flavours are 2.17 ounces). I couldn't wait to find them in stores locally, so when I saw a box of them posted on eBay, I bought them right away.
        From the outside of the package they looked like Sour Skittles, which of course gets my mouth watering immediately. The images show a softly sanded set of Skittles, my guess was this was the fizzing part. This sort of fizzing reaction is the same as AlkaSeltzer or other effervescent tablets. Sodium bicarbonate (baking soda) is mixed with an acidic agent, in this case citric acid. When it's dry, nothing happens but when water (or saliva) wets it, they begin a reaction that results in carbon dioxide (the air) and sodium citrate (an alkaline salt with a tangy flavour that works as a mild antacid). I took one Skittle and carefully put a drop of water on it and sure enough as the water wicked around the whole candy the surface started to bubble slightly. It looked like it was being deep fried, or like putting a strawberry in a glass of champagne. It's not like the whole thing got covered in scrubbing bubbles nor would a whole bowl of them create a "snap, crackle, pop" but it's still a remarkable little chemistry demonstration.
        I was expecting the caustic and biting sour coating when I popped two of the Melon Berry flavour in my mouth, and yes, there was a sour tingle, but then there was a fizz. It's not a carbonation fizz, it's more like putting an Alka Seltzer tablet on your tongue. The foaming is soft and has small bubbles which dissipate quickly, especially when I chewed up the candy. I didn't care much for the melon berry flavor as it was, so the additional component was weird and slightly metallic. The Raspberry went nicely, the sour bite was less noticeable and the foam seemed to support the floral flavours. The coating, I was noticing, has a medicinal mineral salt flavour to it, like eating antacids. Berry Punch had a kind of bubble gum note to it, so the bubbly coating fit right in. It reminded me of a cheap soda from my childhood, in the best way possible.
