Tapioca beverage is a various combination of black or green tea, milk, juice, coffee, and small marbles of tapioca (a.k.a. "black pearl" or "boba", made from Tapioca starch, water, corn starch and natural flavors.) It originated in Tai-Chung City (in Taiwan) around 1981, and soon spread across Asia. In the late 90s, it traveled to North America and has quickly become a raging trendy drink on both coasts. It is perceived as a relatively healthier beverage than soft drinks or coffee, and a lot more fun, too.
