Black coffee with some foam coffee is not easy to spill.

It is not easy for bleary-eyed people to bring a full cup of coffee from the kitchen to the restaurant. With the pace of the person, the liquid surface of the coffee will shake constantly, and a little shaking will overflow from the mouth of the cup. However, the situation of lattes covered with foam is different. These foams not only provide creative space for thermal insulation and coffee flowers, but also have excellent shock absorption.
