time capsule
Future message container
A time capsule is a container storing objects or information meant to be opened at a future date, preserving a snapshot of a particular era: The class buried a time capsule with newspapers, photos, and a smartphone.
Time capsules are often sealed during commemorations and opened decades later.
Figuratively, anything that preserves a moment unchanged functions as a time capsule: Her grandmother's attic was a time capsule of the 1950s.
