On the tip of my tongue

On the tip of my tongue: Researchers are developing a lickable lollipop that lets you “taste” in virtual reality games. It’s packed with small gel pouches that mix with your saliva to create flavors like salt, sugar, cherry and even milk. (Ew.) An electrical current triggers the flavors, and the voltage controls how much you get. That means game designers can mix and match for custom tastes.
