    A “virtual (虚拟的) cocktail” glass that lets you change the flavor (味道) of your drink using your Smartphone has been developed by scientists.

    Offering a customizable (定制的) range of drinks and tastes, the Vocktail can change a glass of water into a cocktail at the press of a button. The world's first technology tricks your brain into thinking it is experiencing a specific flavor by fooling your senses of sight, smell and taste.

    Developed by researchers at the National University of Singapore, the glass' three sensory components are controlled via a Smartphone App. Because the software can combine a number of smells, colors and tastes, the Vocktail can create almost any flavor.

    Developer Nimesha Ranasinghe said: “Our approach is to increase drinks flavor experience by overlaying outer sensory stimuli (刺激物). For example, in the Vocktail we overlay color, taste and smell sensations to create an adjustable flavor experience. Flavor is mainly how we feel food and that is achieved through the use of these senses. Therefore, by changing the color of the drink, using different smells and changing the taste through electricity, we are able to copy the flavor of a drink without it actually changing the liquid.”

    The glass houses three fragrance containers connected to micro-air pumps. The pumps release smell that change your feeling of the drinks, flavor. For example, a lemon fragrance will trick your brain into believing it is tasting lemon-flavored drink.

    On the outside edge of the glass are two electrode strips (电焊条) that send electric pulses into your tongue to stimulate your sense of taste and flavor differs with different pulses.
