11 Smells That Are Slowly Disappearing

Nothing can trigger a memory so unexpectedly as an aroma. Clove oil immediately transports you to the dentist’s office. Crayola crayons take you back to elementary school. But some fragrances are being phased out of existence thanks to technology and safety regulations. How many of these do you miss?

1. SPIRIT DUPLICATORS

In 1960s and '70s-era classrooms, it was an olfactory treat whenever the teacher passed out fresh-off-the-machine purple print “ditto” sheets to the class. Virtually every student immediately held the page to his face and inhaled deeply. There was something so pleasing about the aroma that emanated from the printing fluid—a 50/50 mix of methanol and isopropanol. The sole company that still manufactures ditto fluid in the U.S. only sells a few thousand gallons per year these days, as opposed to the over 100,000 gallons they delivered during the 1970s.

2. BURNING LEAVES

A common indicator that autumn was winding down and winter would soon be here was the crisp air filled with the smell of burning leaves. The breeze had a bite to it by the time October rolled around and the ground was sometimes coated with a fine layer of frost, but the smoke from the pile of leaves everyone on the block seemed to burn somehow smelled warm and comforting.

Pollution concerns caused municipalities in the U.S. to enact open burning bans beginning in the 1980s, and today residents are encouraged to either rake and bag their leaves or use them for mulch. Of course, compost piles do have their own aroma, but it’s not particularly enticing.

3. DIESEL EXHAUST

City buses and semi-trucks don’t smell quite like they used to when they accelerate on a cold morning. There are a lot of folks that actually enjoyed the old school smell of the black exhaust these vehicles used to belch. But reductions in the sulfur content of diesel fuel along with selective catalytic reduction gives today’s diesel burners more of a cat urine-y type of aroma.

4. FRESHLY-OPENED POLAROID FILM

Polaroid ceased production of their instant film in 2008. The foil packs used to produce a sweetish chemical-y odor when they were first torn open. It was, in fact, the official “smell” of photography for a lot of kids whose first camera was a Polaroid Swinger.

5. MAGIC MARKERS

The classic glass bottle-bodied Magic Marker was first marketed in 1952, and until the early 1990s, the ink formula included a mixture of Toluene and Xylene, two solvents which not only had a distinctive and not unpleasant odor, but which also contained intoxicating properties when inhaled. Today’s permanent markers get their color from less fragrant alcohol-based inks.

6. BUBBLE GUM CARDS

Topps stopped including a stick of stiff, hard-to-chew bubble gum in their trading cards several years ago when more collectors than kids were buying the product and complaining about the gum sticking to and ruining the bottom card in the pack. So kids today are getting mint-condition cards for their money, but they’re missing out on that distinctive bubble gum smell that wafted from the package when it was opened (and from the cards when they were brand new).

7. CAP GUNS

Even if you didn’t have a toy gun handy, it was easy enough to “shoot off” caps by striking them with a hammer or even a rock. The gunpowder/sulfur smell of an exploded cap is another aroma that immediately propels many minds to summer days spent playing cops and robbers.

8. (OLD) NEW CAR SMELL

That aroma we smell today upon delivery of a brand new set of wheels is very different from the new car smell of 30 or so years ago. A lot of that smell comes from off-gassing synthetic materials, plastics and chemical additives that are used in modern vehicles. In 1960, the average American-made car contained 22 pounds of plastics; in 2012, that quantity had increased to 250 pounds. And there’s also matter of the flame retardants and antimicrobials that are now added to the carpeting and upholstery for additional “safety” (even though some of the fumes have been proven toxic).

9. VACUUM TUBE ELECTRONICS

Old TVs and radios that were filled with tubes instead of transistors emitted a “warm” or hot engine smell as they heated up. If you weren’t particularly fastidious with the feather duster, a fine layer of dust would accumulate on the equipment inside and add a slight burning aroma to the mix. The old movie and film projectors used in schools had a similar smell once the light bulb inside had been burning for a while.

10. TELEPHONE BOOK

Thanks to Google, very few people let their fingers walk through the Yellow Pages anymore when they’re searching for a telephone number or address. Years ago, almost every home and office had a small stack of thick telephone directories (for example, in the Metro Detroit area there were separate books for Detroit, East Area, North Oakland County, and Downriver) that were referred to regularly once Ma Bell started charging for Directory Assistance calls. The inexpensive pulp paper plus the ink and glue in the binding gave the giant tomes a much mustier, paper-y odor than a standard paperback novel.

11. CHALK DUST

Much like cafeteria food and library paste, chalk dust simply smelled like school. With so many classrooms using whiteboards, chalkboard ledges with piles of white powder on them are becoming extinct.

10 Historically Disappointing Time Capsules

Unearthing a time capsule should be an exciting affair, a chance to see mysterious items hand-picked long ago as apposite examples of a bygone era. Unfortunately, these buried tubes of old garbage rarely live up to the hype.

"Ninety-nine percent of time capsules will remain boring as hell to the people that open them," says Matt Novak, who runs Gizmodo's Paleofuture site. Novak is a self-professed time capsule nerd who has seen enough capsule disappointments to keep his hopes in check. "Time capsules are both optimistic and selfish," he tells Mental Floss. "Optimistic in the sense that they represent a belief that not only will anyone find them sometime in the future, but also that anyone will care about what's inside."

Time capsules as we know them are a relatively new invention that became famous in 1939 with the burial of the Westinghouse Time Capsule at the World's Fair. This highly publicized capsule, which is not scheduled to be opened until the year 6939, contains both quotidian items and extensive writings on human history printed on microfilm (along with instructions on how to build a microfilm viewer). It was an ambitious project, with engineers specially designing the capsule to resist the ravages of time. Most time capsules, however, aren't equipped to be buried underground.

"Burying something is literally the worst way to preserve it for future generations," Novak says, "but we continue to do it." Contents are routinely destroyed by groundwater, so most time capsules reveal little more than trash chowder.

Still, Novak holds out hope for "rare one percenters—those time capsules that not only have something interesting inside, but also survived their journey into the future without turning into mush." The following 10 time capsules, however, fall firmly in the remaining 99 percent.

1. Derry, New Hampshire comes up empty

Just this week, residents of Derry, New Hampshire gathered at the local library to witness what they hoped might be an important moment in the town's history: the opening of a 1969 time capsule, which they believed might include some memorabilia from famed astronaut Alan Shepard, who was a Derry native. Instead, they found ... nothing. Absolutely nothing.

"We were a little horrified to find there was nothing in it," library director Cara Potter told the media. While there's no written record of exactly what was inside the safe, we do know that the time capsule had been moved a couple of times over the past several decades. And that the combination was written right on the back. "I really can’t understand why anyone would want to take the capsule and do anything with it,” Reed Clark, a 90-year-old local, told the New Hampshire Union Leader. But local historian Paul Lindemann says that, "There very well may have been valuable items in there" (including something of Shepard's).

2. The past comes alive in Tucson

In 1961, Tucson, Arizona's Campbell Plaza shopping center—the first air-conditioned strip mall in the country—celebrated its grand opening. To make the event truly memorable, developers buried a time capsule beneath the mall, forbidding anyone from opening it for the achingly long time period of 25 years.

When 1986 finally rolled around, another celebration was held for the capsule's unearthing. Three television crews captured the moment when workers, accompanied by a former Tucson mayor, excavated the capsule and cracked it open. Archaeologist William L. Rathje was on hand, and he later reported its contents as "a faded local newspaper (in worse condition than many I’ve witnessed being excavated from the bowels of landfills) and some business cards."

3. Bay City makes peace with its waterlogged history

In 1965, workers at Dafoe Shipbuilding Co. in Bay City, Michigan buried the “John F. Kennedy Peace Capsule.” It was to remain buried for 100 years—until city council members got antsy in 2015 and ordered for it to be unearthed five decades sooner than originally intended.

When crews unsealed the giant capsule, they found it was totally drenched: The shipbuilders responsible for sealing the capsule couldn't prevent it from taking on water. Many of the items were paper ephemera that didn't survive their 50-year submersion.

Non-paper items that could be identified included, according to MLive.com, “an old pair of lace-up women's boots, large ice tongs for carrying blocks of ice, a slide rule with a pencil sharpener, a pestle and wooden bowl, a centennial ribbon, a coffee grinder, a filament light bulb, an old non-electric iron and lots of Bay City Centennial plates, a 1965 Alden's Summer Catalogue, papers from Kawkawlin Community Church, and booklets from the labor council.”

4. Westport Elementary's too-successful capsule

In 1947, the superintendent of Westport Elementary School in Missouri buried a time capsule that wasn't to be opened for another 50 years. He left a note detailing this fact, but he forgot to include any information about the capsule's location. When it came time to retrieve it, no one knew where to start digging. ''We're calling it a history mystery,'' said a teacher who was tasked with finding it. She had little to go on, as the school's original blueprints—like the capsule itself—were lost.

5. The smell of history on Long Island

For its 350th anniversary in 2015, the residents of Smithtown in Long Island, New York opened a time capsule that had been buried in front of town hall in 1965. An unveiling celebration was held, and a crowd of more than 175 gathered to watch town officials dressed in colonial costumes dramatically reveal its contents.

These included, according to Newsday, "a proclamation of beard-growing group Brothers of the Brush, papers, and paraphernalia from the town's 300th anniversary events, a phone book, an edition of The Smithtown News, pennies from the 1950s and '60s, a man's black hat, and a white bonnet.”

Town residents and officials alike came away unimpressed. "I would have thought those folks would have used a little more imagination and put some artifacts from that time in the time capsule," Smithtown's then-supervisor Patrick Vecchio said.

Kiernan Lannon, the executive director of the town's Historical Society, told Newsday, "The most interesting thing that came out of the time capsule was the smell. It was horrible. I have smelled history before; history does not smell like that. It was the most powerfully musty smell that I've ever smelled in my life."

6. A time capsule worse than going to class

In 2014, New York Mills Union Free School District students filed into an assembly hall to watch the opening of a 57-year-old time capsule. The capsule, buried under the school’s cornerstone, was revealed to contain "a 1957 penny, class lists, teacher handbook, budget pamphlet, and letterhead." In a video of the unearthing, you could hear stray boos from disappointed students who expected much more than letterhead.

7. Norway's anachronistic treasure trove

The residents of Otta, Norway had been eagerly awaiting the day when they'd get to open a package that had been sealed in 1912 and given to the town's first mayor in 1920, along with a note: "May be opened in 2012." Townspeople hoped it contained oil futures, while historians optimistically predicted relics from a 400-year-old battle.

The parcel was opened at the end of a lavish ceremony that featured musical performances and speeches. The crowd, which included Princess Astrid of Norway, had to wait 90 suspenseful minutes (in addition to the 100 years since 1912) before they got down to business.

The Gudbrandsdal museum's Kjell Voldheim had the honor of opening the package. Inside he found ... another package. Inside that package were miscellaneous papers, and Voldheim narrated for the crowd as he pored through the items. “Oye yoy yoy," he said ("almost in exasperation," according to Smithsonian), as he tried to make sense of what he was seeing. Included among the lackluster documents were newspapers dated from 1914 and 1919, a few years after the package had presumably been sealed. While deemed authentic, the find was nonetheless confusing.

8. New Zealand's rare find

In 1995, a 100-year-old capsule thought to contain historical documents was opened by hopeful scholars in New Zealand. According to The New York Times, "all they found was muddy water and a button.”

9. Michigan's capitol mess

The Michigan State Capitol celebrated its 100th birthday in 1979, and officials marked the occasion by opening a capsule that had been buried beneath the building's cornerstone. While the itemized list of the capsule's contents was intriguing—"1873 newspapers, a state history, a history of Free Masonry, a copy of the Declaration of Independence, a silver plate inscribed with Lansing officials’ names, and other papers on specialized topics"—it wasn't included in the actual box. The actual items that were buried wound up being destroyed.

“They’re in very bad shape,” Robert Warner, the late director of the University of Michigan's Bentley Historical Library, said. Water damage had ruined the fragile paper documents, and Capitol anniversary revelers had to gamely celebrate a box full of sludge.

10. Keith Urban's time capsule confusion

Australia's Pioneer Village Country Music Hall had been left in disrepair, which is what made the discovery of a plaque on its grounds in 2014 so exciting. Perhaps there was promise buried beneath the abandoned venue. Hidden behind overgrown vegetation, it read:

Pioneer Village Country Music Club
10 yr Time Capsule
Placed by Mayor Yvonne Chapman
This Day 4th July 1994
To be Re-opened 4th July 2004

As recounted by Paleofuture, the capsule's opening was a decade overdue, though fans who used to frequent the music hall said they already knew what was inside: a photo of a young Keith Urban. The musician got his start at Pioneer Village, and the photo was buried to celebrate the local star.

Oddly, a different capsule from 1994 was discovered on the music hall's abandoned grounds in 2013. Keith Urban fans eagerly opened it, thinking they had found the photo, but were left disappointed when it proved to be empty. So, by process of elimination, a photo of Keith Urban had to be in the more recently discovered capsule. Unless there's a third capsule, in which case they should probably just give up and buy a Keith Urban photo on eBay.
