Did you know that if your metal objects are rusting, you can bring them back to life by soaking them in Coca-Cola overnight? The next morning, you'll find that you can easily clean them and even recover their shine!

Rust removal on old tools, screws, cutlery, coins, bicycles, and even car engines is believed to be due to the sodium benzoate present in Coke. This ingredient is a food preservative that inhibits the growth of bacteria, yeast, and mold. Additionally, studies suggest that it acts as a corrosion inhibitor .

Cleaning glass with a dark, sticky liquid? Sounds silly, doesn't it? Well, believe it or not, the citric acid in Coca-Cola makes for an excellent window cleaner. This is especially true for car windows, which tend to accumulate a lot of dirt and debris.

Pour a can of Coke into a spray bottle and apply it to the window surface you want to clean. Rub it with a rag, and if necessary, scrub it with a soft toothbrush. Then, wipe it all off with a damp cloth to ensure no sticky residue is left. Voilà—enjoy your crystal-clear windows!

Since its invention nearly a century and a half ago, Coca-Cola has been the perfect match for a cheeseburger or a slice of pizza. But did you know it can also be used in cooking? Its peculiar and characteristic flavor, along with the sugars and acidity of its secret formula, combine especially well with meats .

It’s ideal for mixing with BBQ sauce to create an excellent marinade or even for baking a whole chicken. Like wine or coffee, Coke can also be used to prepare delicious desserts, such as brownies and ice cream shakes.

Over time and with multiple uses, pots and pans develop a blackened color on the bottom and sides that is difficult to remove.

To restore your favorite kitchen tools to like-new condition, just apply a glass of effervescent Coca-Cola and put it on the stove on low heat. Let it work for at least an hour to loosen the dirt. Then, scrub as usual—you’ll never believe the results!

Everyone knows that grease stains are difficult to remove from clothing. Commercial stain removers can be expensive, contain many chemicals, and don’t always work. But there is a much simpler solution: one of Coca-Cola's alternative uses is removing grease stains from clothing .

Just add a can of Coke to your washing machine cycle or apply it directly to the affected area. Coca-Cola can even help deodorize smelly clothes !

If you have a piece of furniture that has fallen victim to a paint stain —or an innocent marker drawing made by one of your children or grandchildren—and you want to make it look as good as new, dip a rag in Coca-Cola and rub it hard on the affected area.

To finish, simply wipe the area to prevent it from becoming sticky. Yes, it’s as easy as it sounds!

Drain cleaning

There are mixed feelings about the effectiveness of this trick, but there’s nothing better than trying it yourself to see if it works. Many suggest that applying Coca-Cola to drains can help clear clogs . Simply pour a bottle of the drink down the drain and let it work. Then, finish by pouring a cup of hot water down the drain.

You may be wondering: Is there any scientific evidence to support this claim? One of the ingredients in the most famous soda in the world is phosphoric acid , an anticorrosive that, in the case of Coca-Cola, is used for flavor. But don’t worry—the amount of phosphoric acid in Coca-Cola is safe for human consumption!

Insect repellent

No, it’s not about applying it to the skin, but using it as bait . If you’re going to be outdoors in an area with lots of insects, pour a glass of Coke into a shallow dish and let the bugs be attracted by its high sugar content (according to studies, one can contains the equivalent of ten teaspoons). You’ll see how they stay there and don’t bother you.

This alternative use of Coca-Cola is great for reducing the need for chemical pesticides in your garden. You can even pour the leftover liquid onto plants that thrive in acidic soil, like camellias and rhododendrons.

Relief from bites

What happens if you forget to set the Coke bug trap beforehand? If you’re too late and get bitten by a mosquito or a bee, the solution can still be Coca-Cola.

Pour the soda over the bite area (or, better yet, soak a cotton pad and apply it to the specific spot) to help reduce the swelling and provide some relief.

Remove gum from hair

Image: Natalia Olivera

Gum stuck in hair can be a great frustration for parents or grandparents of naughty children. Believe us, a trick like this will save you from a big headache! But how does it work? The phosphoric acid in Coca-Cola reacts with the hair's natural oils, affecting the gum's properties. As a result, the gum won’t be able to adhere to the hair and, with the help of a comb, will come off easily.

While the gum may be easy to remove, the hard part is getting the kid to stay still for the duration of the process!

Cleaning the bathroom

Have you run out of cleaning products and have guests coming over? Don’t panic—that abandoned Coke can at the bottom of your fridge is about to save you from the embarrassment of having a dirty toilet. Coca-Cola can be used to clean bathroom wall tiles, the toilet, and the bathtub.

A simple and practical way to do this is to use the spray nozzle from an old cleaning product, screw it onto a bottle of Coke, and spray the soda on the walls. Wait a few seconds, then wipe with a cloth or sponge... and it will be as good as new.

Make a science experiment

Image: Lucas Santos

Creating a geyser by mixing Coke and Mentos is practically a rite of passage for most kids—it's explosive, messy, and lots of fun! But how does it work?

Strange as it may sound, it's not a chemical reaction but a physical phenomenon . Mentos have thousands of tiny pores that disrupt the polar attractions between water molecules, creating thousands of nucleation sites ideal for gas molecules to congregate. The bubbles increase in size, causing the liquid to shoot out and rise to the surface, creating a spectacular effect that appeals to both children and adults alike!

Home economics class

Home economics as a school subject peaked in the mid-20th century, teaching sewing, cooking, and budgeting —often aimed at girls.

By the 2000s, however, many states had folded it into a broader "family and consumer sciences" category, as shifting gender roles and changing cultural habits made the old curriculum feel increasingly outdated.

2

Woodshop in every school

Lightly supervised children with access to power tools? Today, it seems hard to believe, but woodshop was a standard industrial arts course throughout the 1950s–1980s.

Declines began in the 1990s due to higher liability insurance costs, budget cuts, and a growing emphasis on college-prep academics over practical skills. Some schools still maintain limited woodworking programs, often using them as hands-on, integrated learning tools.

3

The dodgeball era

Dodgeball dominated physical education classes well into the 1990s, often using hard rubber balls that were notorious for causing stingers, bruises, and occasional injuries . The game was popular because it required little equipment, could fill an entire class period, and kept large groups of students active.

By the 2000s, however, concerns about safety and bullying led many districts to restrict or replace dodgeball with more structured team sports. Some schools still play modified versions, usually with soft foam balls and strict rules.

Chalkboard dusting

For over a century, green and black chalkboards were the centerpiece of American classrooms, with students regularly assigned to "clap out" erasers outside to clear the built-up dust. Chalk was cheap, durable, and easy for teachers to use in large rooms.

By the 1990s, districts began replacing chalkboards with whiteboards due to dust concerns linked to asthma and indoor air quality. The shift accelerated as overhead projectors, digital displays, and interactive whiteboards provided cleaner surfaces and reduced inhalation hazards.

5

Daily milk breaks

Mid-morning milk breaks became common in American elementary schools after the USDA expanded dairy subsidies through programs like the Special Milk Program in 1954. For decades, students lined up for small cartons—usually whole milk—intended to boost childhood nutrition and support U.S. dairy producers during periods of surplus.

By the 1990s and 2000s, milk breaks declined as updated nutrition guidelines shifted schools toward broader meal programs rather than standalone milk service.

6

In-school smoking lounges

The idea of teens openly smoking on school grounds would be almost unimaginable under today’s health and liability standards. But through the 1960s and into the early 1980s, many American high schools—especially in the Midwest and Northeast—maintained designated smoking areas for students.

The practice disappeared quickly as federal and state regulations tightened, beginning with widespread adoption of indoor smoking bans in the late 1980s and early 1990s. The 1994 Surgeon General’s report and anti-tobacco campaigns further pushed districts to eliminate student smoking sections altogether.

7

Daily cursive drills

For most of the 20th century, daily cursive drills were a nonnegotiable part of American schooling , often reinforced by specific handwriting manuals. Teachers devoted significant class time to perfecting loops, slants, and connected strokes, because cursive was considered essential for legibility, speed, and personal discipline.

The decline accelerated after the rollout of the Common Core State Standards in 2010, which omitted cursive entirely in favor of keyboarding and digital literacy benchmarks. With shrinking instructional time, cursive was often one of the first skills removed from early-grade schedules.

8

Class pet enclosures

From the 1960s through the 1990s, class pets—hamsters, guinea pigs, turtles, goldfish, and even the occasional lizard—were staples of American elementary classrooms. Teachers used them to teach responsibility, empathy, and basic biology , and many classes created rotating "pet helper" charts for feeding and tank cleaning.

Today, the idea of a live animal in a crowded classroom, handled daily by students, feels out of step with modern safety, allergy, and sanitation standards. Maintenance costs, humane-treatment rules, and the challenge of caring for animals during breaks led schools to retire these longtime classroom mascots.

9

Student hall monitors

For much of the mid-20th century, student hall monitors were a fixture in American schools. Selected students—often upper-grade or high-performing—wore badges or sashes and were tasked with checking hall passes, reporting loitering, and keeping noise down between classes.

By the 1990s, the role faded as schools adopted professional security staff, stricter attendance protocols, and legal liability rules that made peer enforcement impractical. As districts invested in cameras, campus supervisors, and centralized discipline systems, the traditional hall monitor quietly disappeared from most American schools.

10

Morning physical calisthenics

From the 1950s through the early 1970s, influenced by Cold War fitness campaigns, many American schools began the day with school-wide calisthenics —jumping jacks, toe touches, and arm circles—led over the PA system.

The practice faded as schedules tightened and PE moved into dedicated class periods, with research favoring structured fitness over brief daily routines. Today, the idea of entire schools performing synchronized drills feels almost militaristic.

Also known as the Corps of Discovery Expedition, the Lewis and Clark Expedition crossed the newly acquired western portion of the country after the Louisiana Purchase . This group of U.S. Army and civilian volunteers under the command of Captain Meriwether Lewis and his close friend Second Lieutenant William Clark set out from Illinois, on May 14, 1804.

They crossed the Continental Divide of the Americas near the Lemhi Pass, eventually coming to the Columbia River, and the Pacific Ocean in 1805. The return voyage ended on September 23, 1806.

The leader of the Wheeler Survey, George Montague Wheeler, was an American pioneering explorer and cartographer who led one of the major geographical surveys of the western United States in the late 19th century.

In 1872, the US Congress planned to map the portion of the country west of the 100th meridian . This plan became known as the Wheeler Survey, which lasted until 1879 when the Wheeler, King, and Powell Surveys’ combined work was reorganized as the United States Geological Survey.

The Donner Party was a group of pioneers who migrated to California in a wagon train from the Midwest. Delayed by a multitude of mishaps, they spent the winter of 1846-1847 snowbound in the Sierra Nevada .

While the journey west usually took between four and six months, the Donner Party chose to follow a new route called the Hastings Cutoff, which delayed them greatly.
