time capsules

Future-bound sealed containers

Time capsules are containers filled with objects, documents, or other artifacts meant to represent a particular moment in history, sealed and stored for future opening.

The practice emerged in the late 19th century as a way to communicate with future generations, often buried during building dedications or world's fairs.

Schools frequently create time capsules as educational projects, while cities bury them during anniversaries or commemorations.

We buried a time capsule with photos, newspapers, and letters to be opened in fifty years.
