Not all time capsules meet a glorious fate. While some traverse the centuries with elegance, others offer valuable lessons in conservation — and sometimes moments of unintentional comedy that their creators certainly would not have anticipated. Here is a tour of the most entertaining and sometimes most disastrous mishaps in the history of time capsules, from the Michigan mush to obsolete digital technologies.
The Michigan Mush Box (1879)
At the Michigan State Capitol in Lansing, a time capsule had been solemnly placed beneath the cornerstone during the building's construction in 1879. The ceremony had been dignified and official, with the participation of state dignitaries. The detailed list of contents, preserved in the archives, was tantalizing: photographs of the city and its inhabitants, official state documents, newspapers of the day, coins in circulation, and various souvenirs representative of everyday life in 1870s Michigan.
When the capsule was opened for the building's centennial, the disappointment of those present was total and the surprise universal. Water had infiltrated slowly but inexorably over the decades, transforming the precious contents into what witnesses described with disarming frankness as "a box full of mush." The photographs, newspapers, and documents had fused into a shapeless and indecipherable mass. Only a few metal coins survived the test of time and water.
This mishap has become a famous case study in the field of conservation, demonstrating spectacularly that the number one enemy of time capsules is not time or forgetting, but humidity and water infiltration.
The Too-Well-Kept Secret of Wilkinsburg (1962)
The story of Wilkinsburg, a small town in Pennsylvania in the eastern suburbs of Pittsburgh, is perhaps the most absurd and tragically ironic of the genre. In 1962, to celebrate the 75th anniversary of the town's incorporation, a special committee of citizens was formed with the mission of burying a time capsule containing souvenirs and testimonies of local life.
Eager to protect their treasure from vandals, thieves, or the curious, the committee members made a decision that seemed wise at the time: keep the exact location strictly secret, known only to themselves. No map, no plan, no official document mentioned the precise burial coordinates. Security was total.
The problem, inevitable in hindsight, appeared 25 years later, in 1987, when it was time to find the capsule for the city's 100th anniversary. Almost all the original committee members had died in the interim, and the sole survivor, elderly and frail, could no longer remember the exact location. Searches were conducted in suspected areas — parks, municipal grounds, surroundings of public buildings — without the slightest success. To this day, several decades later, the capsule is still lost somewhere beneath the streets and gardens of Wilkinsburg. The irony is cruel: the committee had protected the capsule so well that they protected it from everyone, including themselves and posterity.
The Capsule Forgotten in a Closet (1953)
In Washington State, during an official celebration in 1953 marking the centennial of the territory, two time capsules had been carefully prepared. One was ceremoniously buried as planned, under the approving gaze of officials and citizens. The other, for a reason that nobody ever fully elucidated, was inexplicably left in a storage room on the 5th floor of the State Capitol, tucked in an ordinary crate among other office supplies.
Nobody remembered it. Civil servants changed, archives were lost, and the anonymous crate sat there, forgotten by all, for nearly half a century. It was not until 2001, after the Nisqually earthquake of February 28, 2001 (magnitude 6.8 on the Richter scale, one of the most significant in the region's recent history), that workers carrying out structural repairs to the damaged building found it by pure chance. The contents were fully preserved and in excellent condition — involuntary but eloquent proof that a dry, temperature-controlled closet on the fifth floor is infinitely better than a damp hole in the ground.
The Demolished Safe of General Dynamics (1963)
General Dynamics Astronautics, the aerospace division of the defense giant General Dynamics based in San Diego, California, had placed a time capsule in an imposing reinforced concrete safe during the division's 5th anniversary in 1963, at the height of the space race and the Apollo program. The contents had been carefully selected to document the technological advances of the era, and the intention was clear: open the capsule during a future significant anniversary of the company.
But in the 1990s, when the building was demolished to make way for a new real estate development, no one among the decision-makers remembered the capsule's existence. The division had been restructured, the staff had changed, and the institutional memory had evaporated. The reinforced concrete safe was destroyed along with the rest of the building by bulldozers. The capsule is presumed reduced to rubble, mixed with demolition debris sent to a landfill. A costly and definitive lesson: even a massive safe does not protect against human forgetfulness.
The Beer That Does Not Age Well
The idea of putting beer in a time capsule is a recurring one around the world, and the result is invariably the same: profoundly disappointing. Beer, a living beverage par excellence, simply does not keep over long periods. Over time, it goes flat, oxidizes, develops unpleasant flavors, and becomes completely undrinkable.
The Steve Jobs capsule in Aspen, buried in 1983 during the International Design Conference, contained for example a six-pack of beer among its objects representative of the 1980s. When it was unearthed 30 years later in 2013 by the National Geographic Channel "Diggers" show team, the beers were in a state that could charitably be described as not recommended. The same thing has happened in countless capsules around the world. Conservation experts consistently remind us: organic liquids and time capsules simply do not go well together.
The Recurring Problem of Obsolete Technologies
The digital age has added a new and entertaining chapter to the catalog of time capsule mishaps. Many capsules from the 1980s and 1990s proudly contained 5.25-inch floppy disks, VHS cassettes, audio cassettes, or CD-ROMs loaded with data. Major problem: when they are opened a few decades later, the devices capable of reading these media have often disappeared from homes, offices, and even museums.
The case of Yahoo!'s digital capsule particularly illustrates this novel challenge. In 2006, Yahoo! created a collaborative digital capsule in Calabasas, California, inviting Internet users from around the world to submit texts, photos, and videos online. The project, ambitious and innovative for the time, was meant to constitute a collective portrait of humanity in 2006. But after the company's successive restructurings and commercial decline, the project was silently abandoned. The associated website closed, and the exact fate of the digital content submitted by thousands of users remains uncertain to this day.
The International Time Capsule Society (ITCS), founded in 1990 at Oglethorpe University in Brookhaven, Georgia, by Paul Hudson, estimates that approximately 80% of time capsules are lost, forgotten, or destroyed before their planned opening date. This considerable figure is explained by the combination of all the factors discussed above: water infiltration, undocumented demolitions, failing collective memory, and obsolete technologies.
The Lessons to Remember: What Experts Recommend
Conservation and archival experts say it bluntly and with remarkable unanimity: burying an object in the ground is, literally, the worst way to preserve something for future generations. Contents are regularly destroyed by groundwater, resulting in what some specialists call with macabre humor a "waste soup."
The U.S. Library of Congress, the federal reference institution in documentary preservation, publishes detailed recommendations for those who still wish to create a physical time capsule. Their main advice: use a hermetic container made of food-grade polyethylene PET or stainless steel, store the capsule dry and cool (and definitely not buried!), handle objects with cotton gloves to avoid acid and oil transfers from skin, use acid-free archival paper and archival ink for documents, and keep a detailed inventory of the contents in a separate, secure location.
But in the 21st century, the most reliable solution for communicating with the future is perhaps also the simplest: do not bury anything at all.

The lesson is clear: if you want your message to survive time, do not bury it in the garden. With Capsul, your capsule is safely stored, protected, and guaranteed to arrive at its destination. No mush, no forgotten closet, no demolished safe — promised.
