America seals 250-year snapshot in a Philadelphia time capsule to open in 2276

A 900-pound stainless steel time capsule is being buried near Independence Hall in Philadelphia to capture a snapshot of the United States in 2026. It is designed to be opened in 2276, marking 250 years since the nation’s founding, and contains items from all 50 states, five territories, and various organizations, including relics from history and modern touches like an AI prompt and an iPhone, stored in a sealed cylinder with a separate papers compartment to withstand centuries underground.
