A legendary combination of Mountain Dew and Pixy Stix occasionally spoken of in gaming magazines. I do not advise trying to make this; to have a real difference noticable in your Dew, you'd have to add approximately a whole bag of pixy stix, and find some way of mixing them in. The problem is that adding even two pixy stix to a 20 ounce ("Big Slam") bottle of Dew, the soda becomes rather agitated, as though it had been shaken, and will proceed to erupt violently through the mouth of the bottle. Dew is wasted and shoes become damp. No good.
I do like the concept though. Sugar rush + caffeine rush + more sugar rush = sounds like a lot of fun. Damn those chemical reactions.
