Antarctica is the coldest, windiest, and sometimes the darkest place on Earth. And yet hundreds of people go there each year to conduct scientific research and work as support staff at dozens of stations scattered across the continent. In summer, the high season for polar activity, the sun never sets, offering scientists and support teams an opportunity to play soccer on the ice or sunbathe in blinding, cloud-free rays. Winter envelops the land in frigid darkness—and inspires the few "winter-overs" to indulge in naked footraces around the station. Mental Floss spoke to a few Antarctic scientists about what it's really like to carry out research there, including the hacks that help them survive the elements.

1. THEY LEARN ON THE FLY.

Scientists participating in the United States Antarctic Program (USAP), which runs all of the American research and operations on the continent, go through an introductory briefing about living and working at the three American stations: McMurdo, the largest, which is located on Ross Island; Palmer, on Anvers Island off the Antarctica Peninsula; and the Amundsen-Scott South Pole Station.

But with so many complex protocols needed for daily life, new arrivals often find themselves on a steep learning curve. "There's no manual for a lot of things," Michelle LaRue, an ecologist who studies Adélie and emperor penguins and seals in the Southern Ocean and is often based at McMurdo, tells Mental Floss. "There are appointments for everything—food, field supplies, et cetera—and you need a certain amount of lead time before you get into the field. I quickly learned that even though you think you're ready, there's something else you're missing. Thankfully the support crew there is amazing. I don't know what we would have done without them."

2. THEY HAVE TO PACK CAREFULLY.

Gathering everything for an extended mission can be tricky if you can't depend on regular resupply shipments. "Packing for 18 months away is a total nightmare. Ever tried to work out how many tampons you might need for that long? Or conditioner?" ecologist Jess Walkup tells Mental Floss. Walkup began her career with the British Antarctic Survey (BAS) studying albatrosses on South Georgia and is now the base commander at the BAS's Rothera station leading the 2018 wintering team.

"I ran out of anti-perspirant on one trip, and that was awful," she says. "Thankfully I was on an island with just three men and thousands of stinky seals, so no one seemed to notice."

3. THEY HACK THEIR CIRCADIAN RHYTHMS.

Scientists and support staff who serve in the Antarctic summer, from October through March, often contend with round-the-clock daylight. Many bring eye masks and blackout curtains so they can retain their regular sleep-wake schedule—but it's tempting to want to stay up. "After working all day, all I want to do is catch up with friends or go hiking. Time gets away from you pretty quickly, and before you know it, you're going to bed way later than you should," LaRue says.

The Antarctic winter, however, is another matter. The sun doesn't rise for several months, leaving the entire continent in extreme darkness (except for the twinkling of stars and the aurora australis). "I found that I was shattered all day and then slept badly at night," Walkup says. "In the early afternoon I would have a massive slump and feel like it was 3 a.m. and I had been awake for a week." She adjusted by using a SAD lamp on her desk and getting into a routine of winding down and going to bed at the same time each night. On the base, she says, "Your bed is one of the only places you can get some time alone."

4. THEY HAVE STRANGE TASTES IN MOVIES.

It's not all work and no play for Antarctic scientists and staff. The isolation and rough conditions create a sense of camaraderie that is celebrated at certain times of the year. To mark Midwinter's Day in the middle of June (the point when the sun begins its return back south), the BAS bases, the Amundsen-Scott South Pole Station, and many others watch The Thing ("the original, obviously!" Walkup says). In John Carpenter's 1982 horror film, a parasitic alien invades an Antarctic base and steadily takes over the minds of the researchers stationed there, with much gore, violence, and paranoia. Winter-overs also watch the 1980 classic The Shining, a similarly chilly flick featuring an unhealthy dose of insanity.

In August, many of the Antarctic stations compete in the 48-Hour Winter Film Festival, in which teams submit short films that contain five key elements and are made in less than 48 hours. "We then watch all the submissions and vote on the winners under various categories, like at the Oscars. It’s a great way to learn about the international Antarctic community and see the inside of other stations," Walkup says. (Watch a selection from the 2016 festival on Vimeo).

5. THEY MAKE TIME TO PARTY.

Sure, scientists spend many hours tracking neutrinos, conducting wildlife surveys, collecting ice cores, and fulfilling other objectives. But when they're off the clock, they like to kick back. "Depending on the time of year, there's all kinds of iconic parties and events to attend: Halloween, Thanksgiving dinner, the marathon, talent shows, the film festival, IceStock—that's an outdoor concert on New Year's Eve. If you're in McMurdo over New Year's Eve, you have to go to IceStock," LaRue says.

However, some of the games and competitions might seem fatalistic to those with a greater array of entertainment options. For example, when the temperature drops to -50°C (-58°F), scientists and staff strip naked and run around their stations' perimeters, Walkup reports.

Even that's not as crazy as vying for membership in the 300 Club. When the temperature drops to -100°F at the South Pole station, daredevils first warm up in a 200°F sauna, then dash outside (naked, of course) to the spot marking the Geographic South Pole several yards away, then run shrieking back into the sauna—having experienced a 300-degree range in temperature in just a few minutes.

The activities don't just keep boredom at bay; they actually ward off the lethargic, depressive state one gets from living in extreme isolation, which the winter-overs call "toast." As Sven Lidström, a Swedish engineer who helped build the IceCube South Pole Neutrino Observatory, wrote in a 2012 blog post, "the cure for winter-over toastiness is fun and entertainment."

6. THEY START CRAVING SALAD …

According to Jason C. Anthony, author of Hoosh: Roast Penguin, Scurvy Day, and Other Stories of Antarctic Cuisine, much of the culinary history of the southern continent consists of "isolated, insulated people eating either prepackaged expedition food or butchered sea life." Now, 21st-century scientists chow down on three freshly prepared meals a day at McMurdo and other stations. "Of the five seasons I spent in, or worked out of, McMurdo, I only really remember one where freshies"—local slang for any kind of fresh produce—"were in noticeably short supply," LaRue says.

But scientists and staff still have to cope with the lack of some favorite foods—and those whose fitness for eating is debatable.

"We only really get two deliveries of fresh food a year, one around December and then again around March. All our milk is powdered, and I got used to that very quickly. Some people hate it, but in a cup of tea or a bowl of cereal, I don’t really notice. I wouldn’t drink a glass of it, though," Walkup says.

Walkup devised ways to test if months-old foods were still edible. "We were eating eggs nine months after they had been laid," she says. "Some eggs that look moldy on the outside, and even on the inside, are fine to eat. The trick is to break each egg into a cup to check that it is OK—i.e., doesn’t smell—before adding it to whatever you're making. If the eggs are starting to go, then this is vital—you don’t want to ruin your mixture with a bad egg."

They also get some surprising cravings. "The thing I missed was salad, as that doesn’t travel well," Walkup adds. "I was never a huge fan of salad before I went south, but now I love it."

7. … AND BOOZE.

No planes can fly supplies into the Amundsen-Scott South Pole Station for up to nine months of the year, because at temperatures below -50°C, the jet fuel freezes. That leaves the small group of winter-overs to their own devices. The company operating the station supplies the scientists and support teams with huge pallets of wine, beer, and spirits that give rise to a makeshift bar at the Amundsen-Scott South Pole Station dubbed Club 90 South. Phil Broughton, a health physicist who spent one long, dark winter there in the mid-aughts, was its de facto bartender.

He developed a protocol for distributing alcohol: serve enough to help the patrons get through the darkest weeks of winter, and then make sure that those who were completely plastered didn't go home. "The most dire danger in Antarctica is always failure to respect the absolutely lethal environment of Antarctica itself. I was far happier to serve until I could guide [the drinker] over to a couch to pass out than to see him stagger out into the -85°F night," Broughton wrote in a blog post.

Plenty of scientists carry in their favorite spirits, just in case their base runs out halfway through the season. Says LaRue, "Bringing scotch with you is a must."

8. SOMETIMES THEY ACTUALLY FEEL TOO WARM.

Scientists in the field have to wear layers upon layers of insulating clothing, bring more hand and foot warmers than they think they'll need, and stay active to avoid hypothermia. "I distinctly remember one snow machine trip back to town, where the wind was just whipping across our faces, my fingers were numb. It was really cold," LaRue says. "As soon as I parked the snow machine I got off and just ran as fast and as far as I could to warm up."

In the summer season, though, being bundled in Gore-Tex can make them too hot. The extremely dry climate prevents the chilly damp feeling of more temperate regions—and if the sun is shining, its rays bounce off the reflective ice and fry the researchers. "Sometimes you can get really warm and even work in shorts and a t-shirt," Walkup says. "At 79 degrees south it can be -10°C [14°F] in the height of summer, and the sun is really strong, so on a day with no wind it is warm enough to sunbathe—just don’t lay down in the snow."

9. THEY DON'T SEE POLAR BEARS.

Antarctica teems with wildlife: six species of penguins, six species of seal, countless seabirds, and majestic whales are the southern ocean's most charismatic fauna. Scientists won't see any mammals from that other pole, however. Says Walkup, "people always ask me if I have seen polar bears. I haven’t—they only live in the Arctic."

13 Behind-the-Scenes Secrets of Movie and TV Extras

Background actors are the unsung heroes of television. Without them, most movie and TV scenes would be empty and unrealistic. But while we’re obsessed with movie stars, we never hear much about the people moving around behind them—because by design, we’re not supposed to pay them any attention. Here are a few insights on what it’s like to get paid to blend into the background.

1. Extras Are Not Professionals.

The chances of using background acting as a foray into stardom are pretty slim. “You’re not gonna get your big break as an extra,” says Claire Beaudreault, who has been an extra on shows including Orange Is The New Black, GIRLS, and Law & Order: SVU.

Most of the people you see in the background of a film or TV show have other jobs and are just doing extra work for fun. “I didn’t do it because I saw it as some backdoor into acting or anything,” says Jason Feifer, who was an extra in a scene of the 2004 film Jersey Girl. “But there are definitely people who do that.”

And there are always a few extras on set trying desperately to stay in front of the camera. “It’s a silent vie for control,” says Dillon Francis, a Los Angeles-based actor who was an extra on the movie Easy A back in 2010. “It was kind of interesting to watch. These guys would learn where the camera was going and redo their vector so they walked in front of it.” That’s a quick way to get a slap on the wrist from the director or a production assistant.

2. Extras Have to Do a Lot of Hurry-Up-and-Wait on Set.

Days on set can be excruciatingly long, sometimes lasting more than 15 hours and starting at odd times or ending at the crack of dawn. And a lot of that time is spent just sitting around waiting to be used in a scene, or repeating a single shot a dozen times. “There are days you get to set and you wait and wait and you never get used,” says Amy Rogers, a regular extra featured in TV shows including Homeland and Banshee, “or you work all day and the footage never gets used.”

Extras spend their down time in a designated “holding” area reading or playing card games. On the set of Easy A, which was set in a high school, extras had to wear backpacks stuffed with bubble wrap to make them seem full. “A fun way to distract yourself in downtime was to open up your backpack and pop bubbles,” Francis says.

3. What Looks Like Booze On Camera Isn't Actually Alcohol.

While posing as party-goers in bar scenes, extras need something to fill their cups. But film sets are no place for drunk actors, so the props team uses a number of tricks to fool the camera, some less appetizing than others. Apple juice is a good substitute for beer, according to Beaudreault: “Or it’ll be seltzer with a little food coloring in it. There will be bottles that have been cleaned out and their labels removed and fake labels put on.”

“Vinegar is sometimes used to approximate the texture and viscosity of booze,” Rogers says. “You’ll stand there with a glass of vinegar for eight hours.” And because filming can be a long and mind-numbingly repetitive process, nobody has time to replace melting ice cubes, so they’ll use gelatin ice cubes. Or, for the ultimate cheat, plastic wrap can be put in a cup filled with water to resemble crushed ice, according to Gale Nemec, who teaches a workshop for background actors. (This approach also apparently makes for festive centerpieces.)

4. Smokers Get Paid More.

When actors smoke on set, they’re usually not sucking on real cigarettes. On Mad Men, for example, the actors smoked herbal cigarettes that didn’t contain nicotine or tar (which is great, considering Jon Hamm reportedly smoked 74 of them shooting the pilot alone).

Non-union extras usually get paid minimum hourly wage, but according to Rogers, they get a small pay increase if they’re asked to smoke in a scene. “They call that a ‘bump’ in the business,” she says. The same rule applies if your car is featured in a scene. “They want boring cars that will never be noticed on screen,” says Steve D’Avria, an extra in The Hunger Games and Homeland. “My 2003 Toyota Camry has been in more TV shows than I have. You get a whole $20 for it.”

5. Extras Have Been Wearing the Same Duds for Days ...

On a film or TV set, continuity is key. To create the illusion that a scene is happening in real-time, rather than over a series of hours or days, every little detail must remain the same in each shot and from every angle. Extras are meticulously examined for accidental inconsistencies in their wardrobes. “You’ve gotta wear the same clothes every day,” Rogers says. “The production assistant will take your picture for continuity to make sure you haven’t taken off a necklace or something. For the Homeland finale, I wore a pair of leggings and a raincoat for a solid week.”

6. ... And They Usually Have To Bring Their Own—The Blander, The Better.

Background actors are usually expected to bring their own clothes to set unless the production has a large wardrobe budget. And if you were to peek into the closet of a regular background actor, you’d see hangers upon hangers of gray and dark blue clothing items. Muted colors are preferred on set to make sure extras are as unremarkable as possible. Shirts can’t have any visible logos, and white clothes are discouraged because they “have a tendency to shine like a beacon on camera,” Francis says.

If you resemble one of the principal actors, you’re probably not going to get much camera time. “On Homeland, you’ll never see them place anyone near Claire Danes who has the same hair color as her,” Rogers says.

And pro tip: never look at the camera. “One guy in The Hunger Games kept staring at the camera and they finally just told him he had to sit down,” D’Avria says.

7. Wardrobes for Extras Get Recycled.

If an extra has to wear an elaborate costume, there’s a chance it’s been used before on another set. “One outfit I wore for Insurgent was worn on Pirates of the Caribbean,” says Dawn McHargue, who has also appeared in The Hunger Games, Iron Man 3, Nashville, and Necessary Roughness.

8. Extras Are Great Mimes.

Extras often need to make a scene appear alive and bustling while at the same time remaining totally silent on set so as not to interfere with the actors’ dialogue. This means pretending to conduct a conversation without actually making any noise, and every extra seems to have their own method. “I’m either pretending to flirt with someone or gossiping about something,” Beaudreault says. Also, dance scenes are often filmed in silence and the music is added in later.

While filming a crowd scene for the movie Jersey Girl, Feifer says he spent hours pretending to applaud and cheer. “They would do entire takes where the audience would go through the whole motion but we wouldn’t clap. We would fake clap but not actually get our hands to meet.”

9. For Actors, Seasons Are Irrelevant.

It’s amazing what a little fake snow can do to transform a summer day into a winter wonderland. “Sometimes when you’re shooting a winter scene, everyone is in heavy jackets and hats and gloves and it’s actually 100 degrees outside,” Nemec says. “You can gauge whether it’s actually cold or not if breath is coming out of the actor’s mouth. If not, it’s a good bet they’ve put snow on the ground and it’s hot as all get out and everyone is playing like it’s cold.”

For indoor scenes, air conditioning has to be turned off to eliminate background noise, which makes for a sweaty situation. Between takes, overheating extras strip their layers off to cool down.

10. The Movie Stars Are Off Limits for Extras ...

“As a general rule, don’t speak to them unless they speak with you first,” advises casting director Tona B. Dahlquist.

While filming on one movie, McHargue and her fellow extras were told to avoid looking the star in the eye. “They were very adamant that we were not to go near him or touch him or we would get kicked off set immediately,” she says.

But occasionally extras get a candid glimpse of a movie star’s true personality. For example, while filming The Hunger Games, D’Avria saw Jennifer Lawrence chilling at a card table munching on M&Ms, and watched Josh Hutcherson (who played Peeta) ride around set on a BMX bike.

On the flip side, Francis was the victim of one star's on-set meltdown. “She sees me standing there and she freaks out, saying something about how she’s had a rash of stalkers lately and I’m within a 50-foot perimeter,” he says. “She’s glaring at me from the tent and a PA runs over, moves me a few feet away and says ‘sorry’ and runs away again.”

11. ... And Social Media Is a Good Way for Extras to Get Blacklisted.

Phones aren’t allowed on set and photos are strictly forbidden. “While filming Insurgent, there was a girl who took a picture of the set and shared it,” McHargue says. “Lionsgate security came from California to Atlanta and they took her away. She will never work on a set again. She’s blacklisted.”

If you’re sneaky, you can swipe a harmless item from set as a keepsake. While filming The Hunger Games, D’Avria says there were signs in the bathroom that said, “Flush the toilet or you’ll be sent to the Hunger Games.” “I borrowed that sign as a souvenir,” he says.

12. The On-Set Catering Is Pretty Good.

The quality of food on set varies depending on budget, but generally, extras eat some amazing grub brought in by professional caterers. “The food on Iron Man 3 was the best food I’ve ever had,” McHargue says. “We ate with the cast and crew and we had anything you could think of: the best steak, shrimp, lobster, and crab. The buffet table, you couldn’t see the end of it.”

The catch: You often don’t get to eat lunch until about 3 pm and dinner starts at 10 pm, according to D’Avria. Extras are advised to bring a few snacks to hold them over until feeding time.

13. Extras Can't Watch TV Like Regular People.

Once you know how a movie is filmed, it’s hard to watch it with fresh eyes. “I can’t watch TV anymore without looking at the background actors and seeing who’s doing it right and who’s doing it wrong,” Nemec says.

15 Secrets of Sesame Street Puppeteers

For 50 years and more than 4500 episodes, Sesame Street has been imparting valuable moral, ethical, and social lessons to young audiences using a sprawling cast of puppets. The Sesame characters—Big Bird, Elmo, Oscar the Grouch, Cookie Monster, Bert and Ernie, the Count, and others—have become instantly recognizable to generations of viewers. But behind every memorable character is a human performer, one tasked with juggling the technical demands of puppet operation without losing the humor and heart that makes their furry counterpart so memorable.

To get a better sense of what goes into this unique skill set, Mental Floss spoke with three veteran Sesame Street performers during the show’s semicentennial celebration. Here’s what they had to say about crossed puppet eyes, grooming habits, and enjoying a long career finessing felt.

1. Sesame Street puppeteers usually get started lending a (right) hand.

Though there’s no definitive set of directions for puppeteers to get to Sesame Street, a number of performers selected to work on the show begin as apprentices with one specific task: operating the right hand of characters alongside the veteran cast members. “A lot of performers will almost only do right hands for a very long time,” Ryan Dillon, the puppeteer behind Elmo, tells Mental Floss. “Some characters, like Cookie Monster, require two performers with two practical hands.”

Dillon started working on Sesame Street in 2005 at the age of 17. He performed as a right hand and as supporting characters for years before scoring the Elmo role in 2013. Throughout that training, he accompanied the main puppeteer, who uses their dominant (usually right) hand to control the mouth and the other to control the left hand. The newcomer will manipulate the right, a duty informally known as right handing. “It’s a great training ground,” Dillon says. “You’re working directly next to a performer with years of experience. You become one character together.”

2. Sesame Street puppeteers have tricks for making their characters emote.

Peter Linz, who portrays Ernie (among other characters) on the series, tells Mental Floss that getting a puppet to exhibit a personality takes some finessing. “You have to show the entire range of human emotion through something that doesn’t have an expression,” he says. Linz, who also teaches classes on puppeteering, says that there are some techniques to get puppets to show off their mood, however. “You can make them look sad by having them look down. You can get them to smile by opening their mouth. If they’re angry, maybe you close their mouth and then shake their arms ever so slightly. There are degrees of subtlety in all of that.”

Linz says the audience does part of that work themselves, projecting their own feelings onto a puppet. The ultimate proof might be in the example of Miss Piggy. While not a Sesame Street cast member, Linz says it’s telling that people often seem to believe the vivacious and flirtatious porcine character bats her eyes. “She can’t,” he says. The puppet doesn’t have that ability.

3. Not all Sesame Street puppets can perform the same tasks.

Sesame Street utilizes three major varieties of character. There’s the full-body puppet, like Big Bird and Snuffleupagus; “bag” puppets with two articulated hands, like Cookie Monster; and hand-and-rod puppets that have arms controlled by thin rods. “Elmo is a hand-and-rod puppet,” Dillon says. “[The difference means] some puppets can do things others can’t. Cookie Monster can pick things up. Elmo can, but it takes longer. You need to stop [filming] and attach something to his hands with tape or a pin.”

4. Sesame Street puppeteers rely on a key design element to connect to their audience.

It can be difficult to communicate that a puppet is able to focus a pair of fixed eyes on something, whether it’s another character, an object, or the audience. But Linz says that the Sesame Street crew and the rest of the Muppets were designed by Henson with that in mind. “The eyes are just two black dots against a white background,” he says. “But all the characters are ever so slightly cross-eyed. There’s a triangle between the eyes and nose and a point where it looks like they’re looking right into the camera.” It’s a sensitive illusion. Turning the puppet even slightly, he says, and they will wind up looking at something else.

5. Sesame Street puppeteers can spend their entire day crouched on the floor.

Being a Sesame Street puppeteer requires more than just having performing chops. On set, characters that may be at waist level with their human co-stars are operated by performers crouched below frame, often on wheeled boards called rollies. “The first day or two, your back and everything else is sore,” Dillon says. “It engages your whole body. Your arm is up in the air performing.” Some actors, Dillon says, have developed knee issues as a result of a career bent over. Fortunately, not every scene requires contortions. Some sets are built raised so performers can stand up straight. Other times, they’ll have to situate themselves horizontally. Scenes set on a stoop usually mean the performer is lying down behind the steps.

6. Sesame Street puppeteers have input into character design.

Lurking in the offices of Sesame Workshop is a puppet factory that, according to Dillon, houses a number of "Anything Muppets"—blank designs that may one day be used as the template for a brand-new character. In 1991, performer Carmen Osbahr got an opportunity to get in on the ground floor of conceptualizing a character when she helped originate Rosita (top right), the first regular bilingual Muppet on the series. “They had a meeting and asked what I had in mind,” Osbahr tells Mental Floss. “I was able to tell them I wanted a monster and I wanted live hands because I wanted to be able to play a musical instrument. I wanted her to be active and colorful. I didn’t want a petite, tiny little monster.” Both Osahr and Rosita have been a presence on the show ever since.

7. Sesame Street puppeteers have material for a blooper reel, but you’ll probably never see it.

Puppet manipulation takes concentration and effort. Occasionally, the cast of Sesame Street can find themselves flubbing a take. According to Osbahr, that’s often due to trying to coordinate left and right hands. “The main thing is props,” she says. “Grabbing stuff is easy, but if you want to pour something into a cup or write a letter, that’s hard. You think you’ll have a glass but just miss it.” Performers can also fall off their rollies, sending their counterparts tumbling out of the frame.

8. Each Sesame Street character has a dedicated puppeteer—with a couple of exceptions.

When it comes to Sesame Street characters, there is one sacrosanct rule—aside from right handing, no puppet will have more than one puppeteer. “We feel strongly each Muppet has a dedicated performer,” Dillon says. “If there were two or three Elmos, you would see a copy of a copy.” However, illnesses or personal appearances can make that rule difficult to follow every time. If Dillon can’t make a shoot, a performer will step in to operate the puppet, with Dillon going in to provide the voice later.

The cast can also cover for one another if a scene requires two characters who are normally operated by the same actor. Both Bert and Grover, for example, are played by actor Eric Jacobson. If the two share screen time, Dillon might step in to perform one of them, with Jacobson recording his lines later.

9. Sesame Street puppeteers have a specific way of handling their puppets to keep them clean.

Day after day of manipulating puppets can lead to issues with cleanliness. Performer sweat can dampen the foam insides, while body oils and other contaminants can affect their fur coats. To avoid being dirtied, Linz says performers and production members try to pick up the puppets by the scruff of their necks. “We don’t want to put our oily hands on their faces,” Linz says. Puppets are also usually delivered to and from the set by a team of “Muppet wranglers,” and stored in the workshop where they’re built and maintained. To dry out a puppet, they’re sometimes placed on a wooden stand. A hair dryer set on low might also be used to dry a sweaty interior.

10. Sesame Street puppeteers work very, very closely together.

Owing to the frequent proximity of puppets in frame, Sesame Street puppeteers are usually working near or virtually over other performers. “We try to be very aware and conscious of the people around us,” Dillon says. “Mistakes happen. Elmo has big feet, and Abby Cadabby has big feet, so you’ll often hit the other person with a foot. It doesn’t hurt.”

11. Guest stars will talk directly to Sesame Street characters—not just the puppeteers.

Sesame Street has played host to many guest stars over the decades, from actors to First Lady Michelle Obama. According to Osbahr, their human guests will often address the character even off-camera. “Most everybody who visits us talks to the character like they’re alive,” she says. “The moment we bring a character down [to rest], we have a conversation, but it’s great to have a relationship with a character and a celebrity. They’ll talk to Elmo, Rosita, Cookie Monster, and we’re talking to them right back.”

12. Sesame Street puppeteers can take years to get fully comfortable with a character.

For many performers, it can take years before they feel like they’re fully inhabiting their character. “You can be so focused on doing something right, you forget to have fun with the character,” Osbahr says. “By the fourth season, that’s when I started letting go, taking risks, having fun. You stop having to think about it.”

Fortunately, it’s not uncommon for performers on Sesame Street to spend decades on the show, which means there's plenty of time to adjust. Carol Spinney, who portrayed Big Bird and Oscar the Grouch, retired in 2018 after 49 years as a cast member. Osbahr says the familial atmosphere encourages longevity. “I’ve been with this group of people for 30 years,” she says. “We’ve shared a lot of incredible memories together.”

13. Sesame Street puppeteers can sometimes mourn a puppet who is declared “toast.”

Made of foam and other delicate materials, Sesame Street puppets have a shelf life. Depending on use, wear, and handling, they might last a few years before needing to be replaced. Linz says two new Ernies have recently been made after one began sloughing off foam inside, a symptom the production calls “toast” because the foam resembles toast crumbs.

Even with replacements, the legacy of characters can still live on. Linz uses an Ernie with the same mouth plate that was used by Jim Henson as far back as 1982.

14. Sesame Street puppeteers have to work backward.

The most surprising aspect of working as a Sesame Street puppeteer? According to Linz, it’s the fact that performers often have to essentially work backwards. Because they’re crouched below the camera frame, puppeteers need to watch a monitor placed low to the ground to see what the camera sees. “When you move your arm to the right, the arm on the monitor moves to the left,” he says. “You’re seeing the image the audience sees.”

15. Yes, Sesame Street puppets are technically Muppets.

Sometimes there's confusion over whether the puppets that appear on Sesame Street actually constitute Muppets, or whether that term is reserved for non-Sesame projects like The Muppet Show or other endeavors featuring Kermit, Miss Piggy, and the others. According to Dillon, any Henson-birthed or -inspired puppet is a Muppet. “It’s become a catch-all term for puppets,” he says. “It’s a brand name, like Kleenex. Jim Henson came up with the name. A Muppet is used for characters that he came up with."
