Japanese drinks giant Kirin Holdings will start selling an electrified spoon that researchers claim can promote healthier eating by enhancing salty tastes without extra sodium. Monday's product launch marks the first commercialisation of technology that last year won an Ig Nobel Prize, which honours unusual and whimsical research. Kirin will sell just 200 of its Electric Salt Spoons online for 19,800 yen ($127) this month and a limited run at a Japanese retailer in June, but is hoping for 1 million users globally within five years.
