Holy Crap, if this is real then... wow.

Seriously.  Makes lemons taste like candy? Come again?

ThinkGeek has the most incredible item for sale.  Perhaps you've seen it, but it's these tablets of a chemical that alters your tastebuds for a while, making sour foods taste sweet.  Apparently the chemical reacts with acids, altering their chemical structure just enough to fool your tongue.  One must remember, however, that the tasting experience does not mean that the acid has been neutralized.  Your normal perception of "how much acid did I just ingest" sensor will be ... malfunctioning for a while.  In other words, try not to rip the crap out of your mouth.

Life-changing.  I mean, if it's real.
