Remember Crystal Pepsi? I don't, that was a little before my time (I think!). Well, they recently re-released it! I found one at my local grocery store, it was the very last one! What better thing to do with this clear, carbonated treasure than to drink it and burp for you!?! I start to drink it slowly, letting a few little burps at a time. Then, when I have half the bottle left I chug the rest of it very fast and burp pretty loud. I am proud of these belches. I rub my tummy the whole time to coax out the gas and as always, it works!
