America250, the nonpartisan organization overseeing U.S. semiquincentennial events, will seal a time capsule on July 4 containing items from all 50 states, the District of Columbia, five territories, the federal government, and partner organizations. The capsule is scheduled for burial at Independence National Historical Park in Philadelphia and reopening in 2276. Specific contributions include an Arkansas diamond, a Maine whale bone, an iPhone 17 Pro Max, and various cultural and state-specific objects.
