Taste works like a piece of music, with just 7 notes, you can make endless unique combinations. With taste, it’s about the five basic tastes: sweet, salty, acidic, sour, and umami. Every dish contains a combination of these with the intensity varying depending on the dish. So a pecan pie and a hamburger both contain all five tastes, but in varying amounts.
What does this have to do with the Internet?
Enter the Norimaki Synthesizer. Developed by a researcher at Meiji University in Japan, has created a “taste display” that can artificially simulate any flavor. A taste machine!
As such, the Norimaki Synthesizer has five gels (one for each taste) that are arranged by an electric current. Through a process called electrophoresis that I cannot possibly explain, the electric current sorts the gels so that a desired amount of each is drawn towards the user’s tongue while the rest of the gel retreats away from the device’s opening.

Tests have indicated he machine is effective, fooling users to think they’ve tasted sushi, or a piece of gum.
Why It’s Hot: Nowhere near being mainstream, the taste tester could have a myriad applications. It won’t be a substitute for the real thing, but it could open a new way for consumers to “try” products remotely or it could be paired with environmental food initiatives to try to substitute environmentally unfriendly practices without losing taste.
