I'd be happy to give you some editing suggestions for your interesting comparison!
"There are some things in life that money can not buy." - Although it is not technically "wrong" to make two words of it, it is a much more universally accepted form to make "cannot" one word.
"creating happiness in ones mind. " - "one's" is possessive, so add an apostrophe whenever you refer to "one's" anything. (Don't do it if you are talking about a bunch of threes, fives and ones! :-))
"the flavor of each individual candy placed into one's mind. " - You are creating some very vivid imagery in this section, which is great! However, the "flavor" is placed on the tongue; it sounds a little off to say it is "placed" in the "mind."
"divulging into a burst of flavor" - Since "divulging" means to disclose something private, perhaps a better word here would be "bursting."
"their so-called fabricated unreal-love." - This sounds a little overworked; in order for it to be "so-called," someone would have to actually call it that. I've never heard a commercial for the "fabricated unreal love" of Starburst. You could just take out "so-called," but the rest of the phrase sounds like you are stretching to find something clever to say. It's better to keep metaphors within the bounds of reason, so that they ring true.
"They create an amazing presence, beautifully shown through the flavor that it has made." - You are mixing plural and singular; say, "the flavor they have made" (or "created").
"normality's" - If you keep this word, spell it "normalities"; however, I don't think it's quite what you meant. "Attributes" would be closer.
"soft candies that makes for an immediate example of their likeliness. " - This doesn't make sense, I'm afraid.
"manipulating the person into believing they are on a rainbow" - This exaggeration rings false; maybe better would be "seducing the consumer into a feeling of flying above the rainbow" or something like that.
"at the same time as Starbursts creating a feeling of an energetic, constructive mood that one will burst in an inferno of a sweet, sourly, and chewy feeling of their own mind" - Rather than "at the same time as" just say "while Starburst creates ..."; also, it's "sour" you want here, rather than "sourly."
"showing its dominance above these two candies." - Say "between" instead of above.
Very descriptive! Good job (and now I am totally jonesin' for some Skittles...)!
