A time capsule is a container that holds items or information meant to be preserved for future generations. Typically buried or sealed in a specific location, it serves as a snapshot of a particular time, culture, or event. Common contents include letters, photographs, newspapers, and everyday objects that reflect the era in which they were created. Time capsules can be created for various reasons, such as commemorating a significant event like a centennial celebration or marking the opening of a new building. They are often opened on a predetermined date, allowing people to connect with the past and learn about their history.
