"Bubble drinks are usually cool, refreshing, and a sweet drink with tapioca pearls sitting on the bottom of a clear cup. Sometimes the drink is made with fresh fruits, milk, and crushed ice to create a healthy milk shake. You can also find drinks that are made of powdered flavoring, creamer, water, and crushed ice. And if you like it like the Asians do, the cool drink usually includes a healthy tea, infused by a flavoring. Tapioca pearls are black, but can sometimes be found to be white or transparent. Depending on the ingredients of the pearl, the color varies. I've been told that the white and translucent pearls are made of caramel, starch and chamomile root extract. The black pearl includes sweet potato, cassava root and brown sugar, which add the black color.

The consistency of tapioca pearls are somewhere between jell-o and chewing gum. They are the size of a marble. They are also known as the "boba" drink in Western China because it is described as to having the same texture as the female breasts."
