Coca-Cola bottle, iPhone, DNA archive sealed away until 2276 in America's 250-year time capsule

PHILADELPHIA, PENNSYLVANIA: On Saturday, July 4, while millions of Americans celebrated the nation's 250th Independence Day with fireworks and parades, another tribute to the country's history was quietly placed beneath the ground in Philadelphia. 

A nearly one-ton time capsule packed with modern-day treasures, including a Coca-Cola bottle, an iPhone, priceless historical records preserved in synthetic DNA and artefacts from every corner of the country, has been sealed for the next 250 years.

It is not expected to be opened until America's 500th birthday in 2276.

A gift to Americans centuries from now

The capsule was buried at Independence National Historical Park during the nation's semiquincentennial celebrations, turning one of America's most historic locations into the resting place of a message for future generations.

Rather than focusing only on famous documents or political milestones, organizers assembled a collection intended to answer a simple question: What did America look like in 2026?

Once sealed underground, the waterproof capsule will remain untouched for two and a half centuries before it is finally opened in 2276.

An art installation inspired by Benjamin Franklin's famous "Join, or Die" illustration now marks the burial site.

The time capsule contains nearly 200 artefacts representing all 50 states; Washington, DC; the five inhabited US territories; all three branches of the federal government; and contributions from everyday Americans.

The contents reflect both everyday American life and the country's technological achievements.

Among the most recognizable items is a commemorative Coca-Cola glass bottle, included alongside memorabilia celebrating one of America's most iconic global brands.

Sitting beside it is an iPhone 17 Pro Max, chosen to represent the technology that shaped everyday life during the country's 250th anniversary.

The collection also includes a crystal from the 2026 Times Square New Year's Eve Ball, a commemorative American flag from the 2026 Rose Parade, student essays and artwork, sports collectibles, and numerous personal contributions from citizens across the nation.

Instead of creating a museum of famous political artifacts, organizers sought to preserve the objects that ordinary Americans interacted with every day.

Tiny DNA capsule protects priceless history

Perhaps the most remarkable object inside the time capsule is one few people would even notice at first glance.

The Library of Congress contributed a tiny metal vial containing synthetic DNA capable of storing digital copies of priceless historical records.

Encoded inside are some of the nation's most treasured materials, including Thomas Jefferson's draft of the Declaration of Independence, an 1898 recording of the anthem performed by John Philip Sousa's band, a three-dimensional rendering of Abraham Lincoln's hand, and several other rare archival items.

The microscopic storage device demonstrates how modern science can preserve enormous amounts of information in an incredibly small space for generations to come.
