In short its a fruit that when comes in contact with taste buds, it alters them in a way that makes sour things taste sweet, pretty cool right? They've been on the Earth for centuries but they're just now starting to make an impact on the world with their new-found popularity. So much so that they've been converted into tablet form.
They're a growing sensation among people. Instead of doing just a party, they take these little babies and have taste testing parties. Just for some info, they're derived from a plant whose scientific name is Synsepalum dulcificum, originating in West Africa. So the next time you hit up a party maybe you should think about buying some of these tablets to make the party all the much sweeter. I personally have an order being shipped to me from ThinkGeek a fantastic website for little things like these.
