Time capsule is a container of items sealed to preserve a record of a particular civilization.
In 1975 and 1976, Americans buried time capsules throughout the United States in honor of the nation's 200th anniversary of independence. The capsules contain articles of clothing, letters, photographs, and other items representing American life in the 1900's. A huge time capsule in Seward, Nebr., even holds an automobile and a motorcycle. It is not to be opened until 2025. W. David Lewis, Ph.D., Distinguished Univ.
