Wafers are thin, crisp snacks made from a mixture of flour, sugar, and water, often baked until they become light and crunchy. They can be enjoyed plain or flavored, and are commonly used in desserts, such as ice cream cones and layered cakes. In addition to snacks, wafers are also used in the technology industry, particularly in the production of semiconductors. These silicon wafers serve as the foundation for electronic components, enabling the creation of various devices like smartphones and computers.
