Hot glue is a type of adhesive that comes in solid sticks and is melted using a special tool called a hot glue gun. When the glue is heated, it becomes liquid and can be easily applied to various surfaces. Once it cools down, it hardens quickly, creating a strong bond. This makes hot glue a popular choice for crafts, repairs, and DIY projects. People often use hot glue for a variety of materials, including wood, fabric, and plastic. It's especially handy for creating decorations, fixing broken items, or even building models. The versatility and ease of use make hot glue a favorite among crafters and hobbyists.
