User: What is Bubble tea?
Assistant: Boba tea is a very delicious drink originally from Taiwan. It started with cold milk tea with tapioca balls in the early 1990s. When the demand gets so popular, the boba tea store owner tries to be fancier by adding different toppings such as grass jelly, pudding cluster, aloe vera, red beans, gummy, mochi and fruit bites. In addition, many store owners become more creative by using different flavors of tea (black, green, oolong, jasmine and other fragrance tea)  as a drink base to outstand other competitors.
