The spacesuit satellite

Shoving an astronaut suit out of an airlock and into space might seem like a scene from a movie, but it really happened. In 2003, an empty spacesuit was thrown into space , nicknamed Ivan Ivanovitch (or Mr. Smith), stuffed with old clothes and a radio transmitter .

The idea was that old spacesuits could be used as satellites. SuitSat-1, as it was named, went on to spend several months in silent orbit before entering Earth's atmosphere and burning up on September 7, 2006.

The "invisible" gorilla

In this strange psychological experiment, researchers asked participants to watch a video of people passing a basketball and count how many passes were made. The catch was that, during the video, a person in a gorilla suit walked into the frame, stopped to pound its chest, and then walked out.

The study revealed a curious phenomenon known as "inattentional blindness": people were so focused on counting the passes that they failed to notice the gorilla .

Space spiders

In 2011, scientists sent two golden silk orb-weaver spiders on a 45-day trip aboard the ISS. They were kept in an adequate habitat, and both spiders adapted beautifully, continuing to spin their webs and hunt for food.

But not everything was normal. In microgravity, the spiders spun their webs differently —flatter and rounder—compared to the more three-dimensional, asymmetrical structures that orb-weavers spin on Earth.

Bitter fingernails

In 1942, a professor conducted an experiment with boys who had been diagnosed as chronic nail-biters. He used a phonograph with the recorded message " My fingernails taste bitter ," playing it over and over at night in the room where the boys slept.

At the end of the summer, the professor examined the boys' nails and concluded that 40% of them had kicked the habit.

In 2004, sixteen people with varying swimming skills swam in both a regular pool and a pool of guar syrup , which is twice as thick as water, for an experiment conducted by the University of Minnesota. The differences in their recorded times were negligible.

Bearcats and popcorn

People encountering bearcats have noted that these animals smell like movie theater popcorn. A non-profit organization tested the bearcat's urine , and the results showed the presence of a chemical compound called 2-acetyl-1-pyrroline.

As it turns out, this is the same compound that gives popcorn its signature smell .

The 28-hour day

Hoping to find out whether the 24-hour sleep-wake human rhythm was merely a habit, two scientists spent 32 days in a cave to avoid any external reference to day and night.

They tried out a 28-hour day, sleeping for 9 hours, working for 10 hours, and having 9 hours of leisure time . The younger scientist adapted within the first week, while the older one failed to adapt.

The fake doctor

A fake doctor delivered a lecture in 1970 to a crowd of assembled experts titled "Mathematical Game Theory as Applied to Physician Education." His performance impressed the audience so much that nobody noticed he was an actor who didn’t know anything about game theory.

The researchers behind the experiment wanted to find out if a great delivery technique could fool a group of experts—and it did.

The electric kite

The most famous experiment on our list is also one of the strangest. In 1752, Benjamin Franklin flew a kite in a thunderstorm to demonstrate the electrical nature of lightning .

While many believe otherwise, no lightning hit the kite. Instead, ambient electrical charge moved through the hemp wire, and when Franklin touched the key attached to the wire, he felt a spark, thus proving the existence of such electricity.

Moon trees

As we've learned, Americans like taking things to outer space and then bringing them right back. The Apollo 14 mission carried hundreds of tree seeds into space . These "moon trees" were then planted across the country by the US Forest Service.

Unsurprisingly, the trees grew just like any other tree of the same species.

Rich Uncle Pennybags

Board games are popular, at least some of them. Clue, Pictionary, Monopoly—we’ve all played at least one of these. But Monopoly’s popularity is something else. And it’s not just the game’s popularity but the fine man who is the face of the brand.

Rich Uncle Pennybags was introduced in 1936 and is widely known as Mr. Monopoly. This rich guy, dressed in a smart tuxedo, turned out to be so popular that he’s been incorporated into the brand’s logo altogether.

Tony the Tiger

Introduced in 1951, Tony the Tiger has been a fixture in, possibly, every single household in the United States and many more countries around the world.

With his classic blue background, Tony the Tiger successfully helped Kellogg’s skyrocket as a brand and made not only the mascot but the cereal truly unforgettable. In spite of being a tiger, Tony is known for his courageous messages and friendly smile that invites consumers to take a scoop of cereal and be ready to face the day.

Gritty

If chaos had a face, it would definitely be Gritty! This wild-eyed, orange furball took the world by storm as the official mascot of the Philadelphia Flyers NHL team.

He made his debut in 2018 and soon became a favorite thanks to his unpredictable antics and meme-worthy expressions, which you are surely familiar with!

Both his personality and his color are quite loud, making him quite unforgettable, as orange is also the color of the team. It represents their essence: unapologetically weird and proud of it!

Smokey Bear

Nature is truly a wonder, but in order to keep it that way, we need to protect it. Now, when it comes to this, warning messages have effectively prevented people from accidentally starting wildfires, thanks to a strong brown bear with a powerful message "Only you can prevent wildfires."

The campaign started in 1944 when Smokey Bear was introduced to the nation to spread the message across radio, TV, and print media. In no time, he became a success and a mighty figure of environmental protection.

Mr. Met

The spring of 1963 must be a loving memory for Mets fans: that’s when their mascot, Mr. Met, was born. And he came to this world with only one purpose, to cheer the New York Mets for life, and oh-boy did he accomplish it!

For over four decades, and with a partner in crime who joined the family in the mid-1960s, Lady Met, this baseball-loving mascot with a giant baseball for a head, has not only been a mascot but has also become part of the family. Is he a part of yours?

Kool-Aid Man

Image: Reba Spike

This brand is one of the most consumed in America and, even though they didn’t need a mascot to be successful, the Kool-Aid man surely brought around a fair dose of cuteness and good marketing.

Originally known as Pitcher Man, which made sense since he is the drawing of a pitcher, he was later renamed Kool-Aid Man with a clear target audience: children. Once again, the brand mascot made it an undeniable success, and it soon became a cultural icon with an iconic "Oh, Yeah!" catchphrase that can make you thirsty just from reading it! Thank goodness we have the Kool-Aid man to assist us there!

The Laughing Cow

This brand has a namesake mascot which, ever since it was created in 1921, has undergone quite an evolution! The cheerful cow, known as the Laughing Cow, first appeared to promote high-quality dairy products when packaged cheese was a novelty.

The character, highly recognizable for its red color, has graced all kinds of the company’s product packages and has become a synonym for quality dairy products, so much so, that it continues to be the logo of the brand today!

Big Tex

If you are from Texas, or if you have attended its State Fair, you are probably familiar with this 55-foot-tall state mascot. Big Tex, the official mascot of the State Fair of Texas was introduced in 1952 as a repurposed Santa Claus figure!

At the time, he was completely transformed into the towering cowboy we all know today. With his classic cowboy hat and his iconic greeting "Howdy, folks!" However, it’s not entirely fair to call him just a mascot, as he actually serves as a cultural ambassador for everyone who visits the State Fair.

Cy the Cardinal

Cereal, cleaning products, sports teams—mascots are everywhere. And universities also have their furry friends. In the case of Iowa State University, Cy the Cardinal is the one and he has been ever since 1954.

Born from a student contest to create a mascot that embodied the school pride, Cy was inspired by the university’s nickname, the Cyclones. He is characterized by his vibrant red plumage and his big smile, which is key to rallying fans at any sporting event. Isn’t he fierce?

Nate Thurmond

In the 1960s and early ’70s, Nate Thurmond anchored the middle for the Golden State Warriors, outmuscling giants and grabbing rebounds as if the ball belonged only to him. Later, with the Cleveland Cavaliers, he became the kind of veteran every young team needs—steady, selfless, and always doing the dirty work that doesn’t make the headlines but wins the crowd’s respect. Both franchises retired his No. 42, a fitting tribute to a blue-collar superstar.

Pete Maravich

Playing in the 1970s, Pete "Pistol Pete" Maravich starred for the Atlanta Hawks and later the New Orleans Jazz. His ball-handling and creativity—whirling passes, deep jumpers—looked like magic tricks that made crowds gasp. After a 10-year professional career and being named an All-Star five times, Atlanta retired his No. 44, and both the Utah Jazz and the New Orleans Pelicans hung his No. 7 jersey.

Moses Malone

Moses Malone was a rebounding machine, plain and simple. He dominated the boards for the Houston Rockets and then the Philadelphia 76ers, where he helped deliver a championship after famously predicting "Fo’, fo’, fo’." Both franchises honored him by retiring his No. 24 (Rockets) and No. 2 (76ers), a fitting salute to one of the game’s toughest, hardest-working big men.

Bob Lanier

Bob Lanier, known both for his silky post moves and those legendary size-22 shoes, was a true powerhouse of the 1970s. With the Detroit Pistons, he combined strength and finesse, scoring with a soft touch and rebounding like a man on a mission. Later, in Milwaukee, he brought the same fire and leadership to a younger Bucks team, proving that experience could be just as valuable as raw talent. It’s no wonder both Detroit and Milwaukee raised his No. 16 to the rafters, honoring a giant whose big shoes came with an even bigger heart.

5

Charles Barkley

Image: Abhay siby Mathew

Charles Barkley was never the tallest guy on the court—just 6 ft 6 in—but with roughly 252 pounds of muscle, grit, and pure attitude, he played like a bulldozer on wheels. Known as "The Round Mound of Rebound," he crashed the boards with fearless energy. In Philadelphia, he became a fan favorite for his fiery play and quick wit; in Phoenix, he shone even brighter, winning MVP and taking the Suns all the way to the Finals. Both franchises hung up his No. 34 as a salute to a player who made hard work look heroic.

6

Earl Monroe

Image: Chaojie Ni

Earl "The Pearl" Monroe brought poetry to the hardwood. In the 1960s and ’70s, his smooth, stop-and-go style made defenders freeze, and fans fall in love. Starting in Baltimore (now the Washington Wizards ), he turned the Bullets’ offense into a show: spin moves, crossovers, and jump shots that seemed to hang in the air. Then came his move to New York, where he teamed up with Walt Frazier to create one of the most graceful backcourts the NBA has ever seen. Both the Knicks and Wizards retired his No. 15 and No. 10: Monroe’s creativity made basketball feel like jazz.

7

Clyde Drexler

Image: Markus Spiske

In Portland, Clyde "The Glide" Drexler soared with effortless grace, gliding past defenders and making the rim look weightless. His mix of speed, style, and quiet confidence made him the heartbeat of the Trail Blazers through the 1980s and early ’90s. When he returned home to Houston in the mid-’90s, he helped secure a championship ring for the Rockets . Today, his No. 22 jersey hangs in the rafters in both Portland and Houston—a lasting tribute to a man who truly lived up to his nickname.

8

Oscar Robertson

Image: Abhay siby Mathew

What if you averaged a triple-double before anyone thought it was possible? Oscar Robertson did just that in the 1960s, stuffing the stat sheet for the Cincinnati Royals (now Sacramento Kings ) and later winning a title for the Milwaukee Bucks, cementing his legacy as one of the game’s all-time greats. Both franchises retired his numbers 1 and 14, honoring the "Big O," one of the greatest players in NBA history.

9

Julius Erving

Image: Abhay siby Mathew

Long before modern dunks, Julius "Dr. J" Erving was taking flight, turning layups into art and slam dunks into poetry. He first captivated fans with the Nets in the ABA before becoming a true icon in Philadelphia . Both teams honored his brilliance: the Nets retired his No. 32 , and the 76ers lifted his No. 6 into the rafters. When you change the game, you don’t just earn a banner—you earn two.

10

Wilt Chamberlain

Image: Tim Hart

Not many players inspire stories that sound too wild to be true, so if basketball had tall tales, Wilt Chamberlain would star in all of them. A 7-foot-1 force of nature, a giant with legendary scoring numbers—including a 100-point game—Wilt’s dominance stretched across the Golden State Warriors, Philadelphia 76ers, and Los Angeles Lakers. All three teams retired his No. 13.

11

Shaquille O’Neal

Image: Luis Montejo

A 7-foot-1, 325-pound tower of strength, Shaq shook backboards, rims, and entire defenses. After playing college basketball, O'Neal was drafted by the Orlando Magic, where he played for four years. Later, he starred with the Lakers, winning three consecutive titles, then helped the Miami Heat capture its first championship. All three franchises retired his No. 32 and No. 34 jerseys, because when Shaq arrived, the fun—and the winning—followed.

12

Kareem Abdul-Jabbar

13

Dikembe Mutombo

Image: Finnian HaDiep

One of the best shot-blockers and defensive players of all time, Dikembe Mutombo protected the paint like a personal fortress. He blocked shots, grabbed rebounds, and smiled through it all. The Denver Nuggets loved him. The Atlanta Hawks loved him. Both retired his No. 55. And yes, fans still remember that famous wagging finger after a big block.

14

Michael Jordan

Image: Abhay siby Mathew

Of course, "His Airness" would be on this list! Michael Jordan’s No. 23 isn’t just a jersey—it’s an icon. In Chicago, it hangs high as a symbol of six championships, clutch shots, and a golden era that fans still replay in their minds like a favorite movie. But there’s more: the Miami Heat have honored his number too, even though Jordan never suited up for them. Call it courtesy, call it class, but wherever you go, No. 23 still means one thing: Michael Jordan was here.
