"America's Legacy in Glass: A 250-Year Time Capsule Journey Begins. In a unique experiment in historical preservation, a time capsule is set to be buried in Philadelphia on July 4, 2026, marking a pivotal moment in American history. As part of the Time Capsule Act, a nonpartisan commission has been working tirelessly to curate a snapshot of modern America, selecting items that reflect the country's progress, culture, and values. Once sealed, the capsule will remain buried for 250 years, to be unearthed in 2276, offering a fascinating glimpse into the nation's past and a testament to its enduring spirit."
The Time Capsule Act, a 2016 law creating the nonpartisan America250 commission mandated that a time capsule be buried in Philadelphia on July 4, 2026, and dug up 250 years later in 2276.
