Electric Fork Zaps Unsalted Food Into Tasty Treat On The Tongue

TOKYO, JAPAN - MARCH 24: An electric fork is displayed on March 24, 2016 in Tokyo, Japan. Researchers unveiled a table fork that electrically simulates saltiness in foods containing no salt, which they expect to see put to practical use for people with high blood pressure. When food is picked up with the fork and placed on a diner's tongue, a weak electrical signal stimulates the taste buds and allows them to "taste" saltiness. Sourness and texture can also be simulated by changing the strength of the electrical signals, but sweetness is difficult to reproduce. (Photo by The Asahi Shimbun via Getty Images)
