Japanese scientists have invented a pair of smart chopsticks. You put a special device on your wrist and the device has a small computer inside. This device connects to the chopsticks.
When food tastes more salty, the sodium ions in food start to move. The chopsticks monitor the amount of sodium in food.
Scientists say that the chopsticks are good for people who can’t eat too much salt. Japanese people eat a lot of salt but of course too much salt isn’t good for the body. The chopsticks can help solve this problem.
