REUTERS/Mohammad Khursheed Starbucks is debuting a new, over-the-top Frappuccino — called the Crystal Ball Frappuccino — on Thursday, according to baristas. The turquoise, peach-flavored Frappuccino is engineered for Instagram and will be on the menu for less than a week. The Crystal Ball Frappuccino follows in the footsteps of the instantly viral Unicorn Frappuccino as Starbucks attempts to reinvent its Frappuccino strategy after a rough 2017.
