Sub Zero Ice Cream and Yogurt will open at 6606 FM 1488, Ste. 110, Magnolia, in late December or early January. The liquid nitrogen ice cream chain offers made-to-order ice cream from a variety of flavors and mix-ins. The chain uses the science of cryogenics to freeze ice cream instantly. Customers choose the cream—what kind of milk the ice cream is made from—the combination of flavors and mixins—fruit, candy, nuts or baked goods—and then watch as the ice cream is frozen with liquid nitrogen. www.facebook.com/subzeromagnolia
