San Francisco may become the next U.S. city to ban plastic straws. The city's board of supervisors approved the ban on a preliminary basis last week and the final decision is on its agenda Tuesday. That has shops that sell boba, or bubble tea – a drink that has to be sucked through a straw – concerned.
Bubble tea is typically served in a big plastic cup over ice. It has balls of tapioca at the bottom the size of small marbles. You use a wide straw to suck up the tapioca — or boba — from the bottom of the cup.
