The variety was fascinating, Tom Medema, a retired National Park Service official and project manager for the time capsule, told The Associated Press.

“I’m glad there wasn’t really a prescription for it,” he said. “I know that was hard for them, but in the end, it was just up to them to represent themselves.”

Some of the items reflect dark historical times, Medema said, as well as the nation’s current challenges. But an air of optimism still surrounded the project.

“There’s great hope in what this capsule represents and the messages that are put in it,” he said. “Something about this capsule has been truly uplifting for everyone who’s been involved in it.”

America250 said the final contents of the capsule will be revealed before July 4. Initial confirmed contents include select items from the 2026 Rose Parade, student submissions from America250’s America’s Field Trip contest, sports memorabilia from national league partners, a handheld flag from an America Waves event, and items from Congress, the Supreme Court and the executive branch.
