A chocolate fountain is a device that melts chocolate and allows it to flow continuously in a cascading manner. Typically made of stainless steel, it consists of a base, a heating element, and a tiered structure where the chocolate flows down. These fountains are popular at parties and events, providing a fun way for guests to dip various treats into the flowing chocolate. Guests can use skewers or forks to dip items like strawberries, marshmallows, and pretzels into the chocolate. The fountains can be filled with different types of chocolate, such as milk, dark, or white chocolate, allowing for a variety of flavors to enjoy.
