If this product ever moves out of the concept stage, Instagram will have a whole new meaning. Chinese student Li Jingxuan has developed a device that is able to print smell along with images. (Because using one sense while looking at pictures was really never enough.)
Here’s how it works: you take a picture of your food, then you use the device to capture its scent. The machine then prints both -- the picture with regular inks, the smell, with a newly invented set of aroma inks. It’s second only to sending the actual food you’re eating, we suppose, but would you use it? At current, the design has no plans for commercialization, so we have some time to decide.
