Lemonade stands may go virtual in the future, if scientists in Singapore can further refine their tasty experiment.
Scientists at Keio-NUS CUTE (Connective Ubiquitous Technology for Embodiments) Center captured the taste and color of lemonade and transmitted it to a remote tumbler filled with water via the internet, according to the CNET report.
The "virtual lemonade" experiment uses electrical currents to simulate the lemonade flavor, but the low voltage doesn't cause any discomfort. Scientists were able to change the color and the taste profile, from mild to sour, in the tumbler equipped with metal strips.
While the concept of digital tastes isn't new, scientists hope this experiment will lead to further iterations that will have real-world usages. For example, scientists hope to create a spoon that carries a salty profile so that hospital patients who need to be on a low-salt diet could virtually flavor their food to their liking.
