Boba; bubbles; tapioca pearls—all terms for the chewy treats that slide up the rotund straws traditionally used to sip Taiwanese bubble tea. Intrigued? Now, thanks to Katie and Dustin Watts's make-it-yourself kit, you can whip up a hot or cold batch of your own. With two flavors of tea—classic black and rooibos chai—tapioca pearls, and two reusable stainless steel straws, this addictive delight is now home-brewable. Just add your choice of milk (or not!) and enjoy. Hand-assembled in Georgia.
