Your beer can tell you where you've been, according to a new study by researchers in Utah. No, not because of the strength of your hangover -- it's all about chemistry.
Beer, bottled water and soda have a natural chemical signature related to geographic location, and drinking them leaves a chemical fingerprint in your hair. The fingerprint could be used to track your travels over time, according to the study, published in the Journal of Agricultural and Food Chemistry.
If you never thought that soda machines would adapt to the high-tech world, think again. Coca-Cola's Freestyle fountain comes equipped with a touchscreen that is able to mix flavors on the spot, using precise machinery originally developed for dialysis and cancer treatments.
There are over 100 flavors available, across an array of drink brands, including Coke, Fanta, energy drinks, flavored waters, and more. When you select a drink, you're able to select from a variety of flavors, some of which are unfamiliar (Raspberry Coke?! Peach Fanta?!).
