Japanese discovered the fork that will replace the salt

The answer to the health problems created by the excessive use of salt, it seems that they gave Japanese scientists through a… fork.
Specifically, the scientists claim that they created an electric fork which with the push of a button releases an electrical discharge that excites the tongue, giving the user the feeling that at that moment in his mouth has salt.
Apart from the feeling of salt-the electric fork can be created, according to the creators, and the sense of sour and metallic.
The Japanese also claims that it only took 12 dollars for the construction of the fork, which is based on the logic that the human tongue feels sour or salty when it comes in contact with electricity.
The fork, which still is not waterproof, created for the group, No Salt Restaurant, which aims to create meals without salt.
He has six hours autonomy and three shades for the salty or the bitter in order to adapt to different tastes.
