With the use of electrodes and sensors -- and zero lemons -- a group of researchers at the University of Singapore have announced that they can convince you that you're drinking lemonade, even if it's just water. Plus, they can send you a glass of lemonade virtually over the internet. In an experiment that involved 13 tasters, the subjects' taste buds were stimulated using electricity from receiving electrodes; LED lights mimicked a lemony color. Some were convinced that the water they were drinking was, in fact, almost as sour as lemonade. According to researcher Nimesha Ranasinghe, the experiment proved that taste can be shared online: "People are always posting pictures of drinks on social media -- what if you could upload the taste as well? That's the ultimate goal." Each of the subjects was given a tumbler filled with a liquid that was either cloudy white, green, or yellow. They were told to place their tongues on the rim of the tumbler before sipping. Then they took a taste and rated the beverage on appearance and taste. Some of the liquids were plain water and some were lemonade. "We're working on a full virtual cocktail with smell, taste, and color all covered. We want to be able to create any drink." Why would anyone want to drink a virtual lemonade? Advocates of virtual eating say that virtual foods can replace foods that are bad for you, that you may be allergic to, or that you shouldn't eat because of a medical condition.
