Ingrediants:

Mountain Dew. I prefer to use diet. You won't be able to taste the difference. Heavily chilled.

Apples, sliced very thin. Preferably with a ceramic knife to prevent browning, bath in lemon juice to prevent browning.

Appletini powdered drink mix. Crystal Light makes this, you can also occasionally find sour apple koolaid. The latter of the two might be better.. atleast less syrupy, but have not tried it.

Apple juice/sour apple juice (*elective*)

Vessels.

If you want the punch to stay fizzy, you will be required to have a vessel that can be sealed air tight, preferably a large one, 5 qts or more.

A punch bowl. Frozen.

Now, before we get on to mixture, we need to talk about chemistry. What gives a soda its fizz is a chemical additive. Some use sodium bicarbonate (baking soda), others use more exotic variants which basically do the same thing. What happens is when the bicarb interacts with acids, they react, creating co2. To see this in it's rawest form, put a few table spoons of baking soda into a bowl, and add lemon juice. Well, soda pop will react in the same way if you introduce a new acid. This reaction will make an unholy mess if you are not careful. For an example, do a youtube search on "myntos and diet coke". Now, chemical reactions have a finite life span, and once the reaction is over, that is all you are going to get out of it. Which means if you are going to want bubbles in your punch, you will need to store your mix in a sealed container, and use it the day it is made, preferably with in the hour. If flat is fine with you, you can just add the ingredients to the bowl.

To mix.

This part is painfully easy. Basically you are just going to add all the ingredients together. I advise adding the apples first, you shouldn't need more then two. just enough to have apples floating around. Then add the powdered mix. You will need one tube of the mix for each bottle of soda. Then add the soda. This will create a lot of foam, which would be neat, kind of like a "cider".....but it will sink back in after just a few minutes, so don't count on it... just stir, or shake, to combine.

Now. Presentation always matters. I suggest taking some decent qulity apple juice, figure out divide it out into 7 different cups. add enough food coloring to each to make the 7 primary colors <roy g biv, red orange yellow green blue indigo violet> then pour each of these out into ice cube trays. you now have awesome rainbow icecubes that won't water down your punch... You can also make an ice bowl by doing the same thing, then inserting a bowl just slightly smaller into your punch bowl, with a cork on each of the four corners to keep the two from resting together at the bottom. Add one color, allow to freeze, add the next color, allow to freeze, and so on, till you have a ring of rainbow colored apple ice. Just for prism's sake, remember the color order. This method does require that you start a few days ahead of time though...

To prevent heat transference you will want to place your punch bowl on a rolled up towel, preferably also frozen the night before. this will insulate the bowl, and also create a small void at the bottom, in which you can place some led white fairy lights, which emit very little heat, but a lot of light. This will make your rainbowl glow which will be about 20% cooler.

Please note any variations you come up with, this is just a basic punch pallet, feel free to shake things up... <yes, you can add vodka to make you punch drunk, but I don't drink, so..>

EDIT TO ADD. IF YOU DO ADD ALCOHOL TO THIS, REMEMBER THAT MOUNTAIN DEW HAS THE HIGHEST PER VOLUME CAFFEINE OF ANY SODA, BESIDES ONES WHICH ARE MARKETED AS "ENERGY DRINKS". CAFFEINE EFFECTS THE WAY THE BODY ABSORBS ALCOHOL AND WILL BUCK YOU LIKE A RHINO!
