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. _This_ [_article_](http://mentalfloss.com/article/58291/11-smells-are-slowly-disappearing) _originally appeared on_ [_Mental Floss_](http://mentalfloss.com/)_._ _More from Mental Floss:_ * [11 Sounds Today’s Kids Have Probably Never Heard](http://mentalfloss.com/article/29230/11-sounds-your-kids-have-probably-never-heard) * [11 “Modern Antiques” Today’s Kids Have Probably Never Seen](http://mentalfloss.com/article/30414/11-modern-antiques-todays-kids-have-probably-never-seen) * [Inside a Top-Secret Factory Where Scent Is Made](http://mentalfloss.com/article/60363/inside-top-secret-factory-where-scent-made) ```json [{"@context":"https://schema.org","@type":"OpinionNewsArticle","@id":"https://time.com/3837031/11-smells-disappearing/","mainEntityOfPage":{"@type":"WebPage","@id":"https://time.com/3837031/11-smells-disappearing/"},"headline":"11 Smells That Are Slowly Disappearing","datePublished":"2015-04-27T21:38:31.000Z","dateModified":"2026-02-22T06:42:55.612Z","description":"Remember how those magic markers smelled?","url":"https://time.com/3837031/11-smells-disappearing/","keywords":["Humor","society","Culture"],"thumbnailUrl":"","author":[{"@type":"Person","name":"Mental Floss","jobTitle":null,"url":"https://time.com/author/mental-floss/"}],"articleSection":"Ideas","image":[],"publisher":{"@type":"Organization","name":"Time","url":"https://time.com/","logo":{"@type":"ImageObject","url":"https://time.com/images/logo.png","width":528,"height":156},"foundingDate":"March 3, 1923","sameAs":["https://www.facebook.com/time","https://www.instagram.com/time/?hl=en","https://twitter.com/time","https://www.pinterest.com/timemagazine"]}},{"@context":"https://schema.org","@type":"BreadcrumbList","itemListElement":[{"@type":"ListItem","position":1,"item":{"@id":"/section/ideas/","name":"Ideas"}},{"@type":"ListItem","position":2,"item":{"@id":"/tag/humor/","name":"Humor"}},{"@type":"ListItem","position":3,"item":{"@id":"https://time.com/3837031/11-smells-disappearing/","name":"11 Smells That Are Slowly Disappearing"}}]}] ```
