Soon, you will be able to taste the food you see on cooking shows. Professor Homei Miyashita made a model TV screen that you can lick. It is called TTTV. This means "Taste the TV". Miyashita said it could become "taste-a-vision". If he created a screen with smells, we would have "smell-a-vision". Miyashita hopes the technology can move on from just having pictures and sound. We will soon have screens on which we can use our sense of taste too.

Professor Miyashita said his screen copies food flavours. It works like an inkjet printer. TTTV uses 10 different flavour cartridges. These spray combinations of flavours onto the TV screen. The TV viewer can lick this to try the taste. The professor said: "The goal is to make it possible for people to have the experience of something like eating at a restaurant on the other side of the world, even while staying at home." TTTV could cost about $870.
