12 Secrets of Roller Coaster Designers

Back in the early 20th century, engineers attempting to push the limits of roller coaster thrills subjected riders to risky upside-down turns and bloody noses. A century later, coaster designers rely on computer software, physics, and psychology to push the limits of the roughly 5000 rides in operation worldwide. To get a sense of what their job entails, Mental Floss spoke with several roller coaster specialists about everything from testing rides with water-filled dummies to how something as simple as paint can influence a coaster experience. Here’s what we learned.

1. Getting strapped in might be the most exciting part of the roller coaster ride.

Known as a “thrill engineer,” UK-based Brendan Walker consults with coaster manufacturers and parks on the psychology of riding the rails. In his experience, riders getting secured into their seats are at the peak of their excitement—even more so than during the ride itself. “The moment the lap bar is being locked down and you have that feeling of things being inescapable, that you have to suffer the effects of the ride, is the highest moment of arousal,” Walker says. “The actual ride might only achieve 80 percent of that excitement.”

2. Designers test roller coasters with water-filled dummies.

Bill Kitchen, founder of U.S. Thrill Rides, says it can take anywhere from two to five years for a coaster to go from idea to execution. Part of that process is devoted to the logistics of securing patents and permits for local site construction—the rest is extensive safety testing. “We’re subject to ASTM [American Society for Testing Materials] standards,” Kitchen says. “It covers every aspect of coasters. The rides are tested with what we call water dummies, or sometimes sandbags.”

The inanimate patrons allow designers to figure out how a coaster will react to the constant use and rider weight of a highly trafficked ride. The water dummies—which look a bit like crash test dummies, but filled with water—can be emptied or filled to simulate different weight capacities. Designers also sometimes use the kind of crash-test dummies found in the auto industry to observe any potential issues prior to actual humans climbing aboard.

3. Every foot of roller coaster track costs a lot of money.

There is absolutely nothing random about the length of a coaster’s track. In addition to designing a ride based on the topography of a park site, designers take into account exactly how much space they’ll need to terrorize you and not an inch more. When England’s Alton Towers park was preparing to build a ride named TH13TEEN for a 2010 opening, they asked Walker exactly how much of a drop was needed to scare someone in the dark. “It was a practical question,” Walker says. “For every extra foot of steelwork, it would have cost them £30,000 [roughly $40,000].”

4. Rollercoaster Tycoon brought a lot of people into the business.

The popular PC game, first released in 1999, allowed users to methodically construct their own amusement parks, including the rides. As a proving ground for aspiring engineers and designers, it worked pretty well. Jeff Pike, President of Skyline Attractions, says he’s seen several people grow passionate about the industry as a direct result of the game. “I remember when the game first got popular, I would go to trade shows and there would be kids looking to get into it using screen shots of rides they designed. The game definitely brought a lot of people into the fold.”

5. Paint makes a big difference in coaster speed.

For all of their high-tech design—the software, fabrication, and precise measures of energy—a good coaster ride can often come down to whether it’s got too much paint on it. “The one thing that will slow down a steel coaster is a build-up of paint on the track rails,” Pike says. “It softens where the wheel is rolling and hitting the track, which increases the drag.” A good, worn-in track will have gray or silver streaks where the wheel has worn down the paint, making it move more quickly.

6. A roller coaster’s skyline is key.

Brian Morrow, former Corporate Vice President for Theme Park Experience at SeaWorld Parks and Entertainment, says that the looming curvature of coasters spotted as guests drive toward and enter the park is very purposeful. “It’s like a movie trailer in that we want you to see some iconic coaster elements, but not the whole thing,” he says. “You approach it with anticipation.”

7. Some coasters arrive as giant model kits.

Whether a coaster’s theme or design comes first is largely left up to the end user—the amusement park. But for some rides, manufacturers are able to offer pre-fabricated constructions that designers can treat like the world’s biggest Erector Set. “Sometimes I work on rides that have already been built,” Walker says. “They’re produced by a company and presented almost like a kit with parts, like a model train set. There’s a curve here, a straight bit here, and you can pick your own layout depending on the lay of the land.”

8. Wooden roller coasters are weather-sensitive.

If you’ve ever been on a wooden coaster that seems a little shaky from one trip to the next, check the forecast: It might be because of the weather. Pike says that humidity and other factors can shrink the wood, affecting how bolts fit and leading to a slightly shakier experience. “The structure itself can flex back and forth,” he says. It’s still perfectly safe—it just takes more maintenance to make sure the wood and fasteners are in proper operating condition. A well-cared-for wooden coaster, Pike says, can usually outlast a steel model.

9. The time of day can affect the coaster experience.

“A coaster running in the morning could run slower when cooler,” Morrow says. “The wheels are not as warm, the bearings are warming up. That could be different by 2 p.m., with a slicked-up wheel chassis.” Coasters experiencing their first-ever test runs can also be slightly unpredictable, according to Pike. "Those first trial runs [during the testing phase] can be slow because everything is just so tight," he says. "A lot of coasters don't even make it around the track. It's not a failure. It's just super-slow."

10. Roller coaster designs can come from unusual places—like Jay Leno’s chin.

The twisting, undulating tracks of coasters can often be the result of necessity: Pike says that trees, underground piping, and available real estate all inform designers when it comes to placing a ride in a specific park. But when they have more freedom, coasters can sometimes take on the distinctive shape of whatever happens to be around the designers at the time of conception. “We had a giant piece of land in Holland that just had no constraints, and we were sitting around talking," Pike says. “And we started talking about Jay Leno’s chin.” The ride was a “loose” representation of the comedian's jaw, but “it is there.”

11. Roller coaster riders double as performers.

For Walker, the best advertising for a coaster is having spectators watch riders de-board after an exhilarating experience. “It’s all about that emotion,” he says. “A spectator basically asks, ‘What’s making them so aroused? What’s giving them such pleasure?’ The line for the ride is the audience. Imagining yourself on the structure becomes a very powerful thing."

12. The future of coasters is vertical.

Biggest, fastest, longest—coasters are running out of superlatives. Because rides can only be designed with so many drips, rolls, or G forces, some companies are looking to the sky for their next big idea. Kitchen has been overseeing design of the Polercoaster for years: It’s a sprawling, skyscraper-esque ride that uses electromagnetic propulsion to carry riders upwards instead of across horizontal tracks. “We want to put it in places where land is very expensive, like the Vegas strip,” he says. “You can only do that if it takes up a lot less space.” The project is set to exceed the 456 feet of the current tallest ride, Kingda Ka at Six Flags in New Jersey. “It’ll be the world’s tallest—and hopefully the most fun.”

10 Behind-the-Scenes Secrets of Professional Songwriters

Behind every club banger and power ballad is an eclectic team of individuals, each with their own role in its creation and promotion. Needless to say, it couldn’t happen without the songwriters. These gifted musicians don’t just pen the lyrics that fuel all your car concerts and karaoke nights—they also manage egos, help artists articulate their innermost feelings, and juggle their own side gigs. So what does a songwriting career actually look like? Mental Floss chatted with three experienced songwriters about everything from how they make money to how they make hits.

1. It’s common for songwriters to have their own music careers.

From Carole King to Pharrell Williams, the music industry has long teemed with talented artists who’ve written songs for other acts—so it’s not exactly surprising that so many songwriters are nurturing what they call their own “artist projects.” In fact, all three songwriters interviewed for this article have released new music in the last few months. Daniel Capellaro released the EP Nightside [A] in November under the moniker “Dvniel”; Skyler Stonestreet’s first single as “The Sunshine State” dropped in late October; and Trent Park has been unveiling a steady stream of singles and corresponding music videos since June.

Though it seems like it could be difficult to constantly fork over songs that they might want to release themselves, the collaborative nature of the business prevents this from being a major issue. Often, the songwriter is working off ideas and emotions specific to the artist they’re writing for, so the song truly feels like it belongs to that artist. Other times, the song gets tweaked by so many writers and producers that it’s no longer the original songwriter’s personal opus. “When a song comes out, sometimes I’m like, ‘Ah that was good, but I would’ve done it a totally different way,” Park says. “But that means it wouldn’t be the song that it is.”

2. Songwriters sometimes have to fake it ’til they make it.

In a business built on relationships, it’s pivotal for up-and-coming songwriters to always be on the lookout for new connections. Sometimes, this means acting first and thinking later. During Capellaro’s early days in Los Angeles, his demo CD was his de facto business card. About a month after giving one to an executive from Universal Music Group, he got a call from the company asking when he was playing next. Having no dates lined up, he picked one at random: March 16. “So I hang up and I'm like, ‘OK, I’ve just committed to playing a show. I've got no venue. I've got no band. I have to get all this put together in the next 30 days,” Capellaro remembers.

He found a former bass player from the band Lifehouse on Craigslist, and the two set about securing the rest of the band. For the venue, Capellaro chose a well-known rehearsal space called SIR (Studio Instrument Rentals), only to find out that the Universal exec slated to see the show “[had] never signed a single act at SIR—she hates that place.” It was too late to switch venues, so Capellaro reassured his Universal contact over the phone that “she won’t recognize it” and immediately transported everything in his recently furnished living room to the stage to give it a whole new look. “I had a couch, a rug, tea candles,” he says. “I wanted it to feel like MTV Unplugged.” The hard-to-please executive was duly impressed. “She’s like ‘You sound great. How long have you guys been playing together?’ and I’m like, ‘Ah, you know, for a while.’ I didn’t want to tell her ‘Four days.’”

When asked what surprised him most about the industry, Park answered without hesitation: “That nobody knows what they’re doing.” He, too, confessed to occasional fibbery. “There are some times when I reach out to an artist and I say, ‘I love your stuff. I have a song for you,'” he says. “I’m completely lying. I just want to work with that person, and once they reach out I end up formulating songs in the vein of their stuff.”

3. Songwriters don’t just write for career music artists.

Songwriters like Capellaro and Stonestreet, who are signed to music publishing companies, mainly do work on songs for fellow artists. Park, on the other hand, is an independent songwriter—so his clients sometimes come from other industries altogether. “Right now I'm writing for a couple lawyers that are just doing it as a passion, but they pay me really well,” he says. “I’m there for everyone. Honestly, it’s way better money.” Park also spent a few weeks writing songs for the wife of a billionaire app developer. Not only did she pay him triple his per-song rate and triple his per-diem rate, she also insisted on posting him up in a luxury hotel and giving him an additional $500 each day for food and other expenses. “That was a really cool [scenario],” Park says, “I’m hoping for more of those.”

4. There are countless ways to create a song—and countless people involved.

Songwriting isn’t exactly a linear process. “You can start from any place,” Capellaro says. “You can start with someone toe-tapping, or have a piano pulled up and just start playing a C chord over and over again.” Often, the record label has already started for you—they’ll send an instrumental track to multiple songwriters, who each adds their own lyrics and melody. Then, the label simply chooses their favorite.

Other songs originate in songwriting camps. Basically, a record label will gather various songwriters in a house, split them into small groups, and “see if magic happens,” Stonestreet says. During a camp meant to generate hits for Dua Lipa a few years ago, it did: Stonestreet and several other writers penned her 2018 single “IDGAF.”

But even after a track has lyrics and a melody, there’s always a chance it’ll undergo another round of edits. Maybe a label liked a certain producer’s work on another song, so they ask them to tweak this one; or they bring in a new writer to fine-tune a few words or add a post-chorus. Big artists also sometimes have personal collaborators that they want credited on the song, whether or not they actually helped create it. “That’s why when you look at a Katy Perry song, you’re like ‘How did 14 people write this one song that has the most juvenile lyrics I’ve ever heard in my life?’ They didn’t—it’s all politics,” Capellaro says.

5. Songwriters don’t make much from music streaming services like Spotify.

Music streaming services like Spotify and Apple Music are notorious for pocketing most of the earnings from artists’ work. Spotify, for example, pays the rights holder as little as $0.006 for each stream—and that paltry sum must then be split among all the people involved in making the song. Songwriters, producers, musicians, managers, label executives, and any number of other people could each be entitled to a certain percentage of the profits. “I have over a million streams on one catalog, and that translated to $785,” Capellaro says. “If I sold a million copies, I would’ve had a house up in [Beverly Hills].” Not only are the rates low, but artists also have to somehow make their songs stand out from the tens of thousands of other new songs released each week, which Capellaro admits is “virtually impossible.”

6. Songwriters often juggle other jobs.

Since songwriters can’t rely on streaming dividends for income—and salaried music publishing positions don’t always come easy—they often make ends meet with a variety of side gigs. Park realized early in his career that while songwriters were mainly earning money from royalties, producers were often paid an hourly rate or up-front lump sum. “So I learned how to produce,” he says. Then, he purchased a mic and other equipment so he could record vocals at home—like hooks for people’s rap or EDM songs. “Basically, I’m an a la carte thing,” he explained. Park eventually branched out into music video production, and he’s now directed videos for chart-topping artists like G-Eazy and Ty Dolla $ign. He also served as a music technical consultant for 2020’s The High Note, starring Tracee Ellis Ross and Dakota Johnson; in that position, he made sure the dialogue, instruments, and other music-related details matched real life.

Even when a songwriter appears to be working a job entirely unrelated to the music industry, there could be a shrewd reason for doing so. Capellaro spent more than a decade running a restaurant called Amici in Brentwood, California. “I knew I wanted to be there because that’s where the celebrities live,” he explains. Sure enough, he connected with people like J.J. Abrams, Laura Dern, and Bonnie Hunt, who was hosting her NBC talk show at the time. One evening while refilling Hunt’s water glass, Capellaro posed a question: “Hey Bonnie, what would it take to be on your show?” She asked if he had a CD on hand, which he did, and booked him as a musical guest within weeks. The day after the taping, Hunt dined at Amici again and lauded Capellaro for his performance. “I’m like, ‘This is so surreal. I was just on your show yesterday, and now I’m bringing you sea bass.” A producer who caught the performance later reached out to Capellaro and ended up inviting him to his studio for songwriting sessions—which yielded hits for Chris Brown and Boyz II Men.

It was also at Amici that Capellaro developed a friendship with Marc Caruso, a music engineer who happened to be the founder of a music publishing company called Angry Mob Music Group. About five years ago, Caruso, knowing Capellaro was itching to give up his restaurant job and focus on music full-time, offered him a music publishing deal; Capellaro’s been there ever since.

7. Songwriters have to form close bonds with artists in a few hours or less.

Because the goal is to create a song that feels personal to the artist, songwriters usually prefer to work directly with them whenever possible. And getting the artist to give them some seed of inspiration means forging a deep friendship with them within minutes of entering the studio.

“There’s so much trust that needs to happen in the room. You’re telling potentially intimate details about yourself that would be uncomfortable sharing [with a stranger]. So much of it is trying to create a safe place for the artist and a safe place for the writers, all the while dealing with egos the size of tall buildings,” Capellaro says. “It’s almost like a therapy session: What’s your mood today? What happened over the weekend? What’re you pissed off about? What’re you inspired by at this very moment? Because it can change at 5 p.m. today, and maybe that inspires the song.”

Stonestreet expressed a similar sentiment. “I honestly love when the artist is involved. You won’t know anything specific unless you’re sitting there having a conversation—it can be emotional. You form a relationship, and you trust each other to handle the information.”

8. Songwriters have to say “no” without actually saying “no.”

Songwriters have to find creative ways of steering a song in the right direction without flatly rejecting an artist’s not-so-great suggestion. Stonestreet might toss out a compliment and lean on the lackluster reaction of the room as evidence that they haven’t yet struck gold. Something to the effect of: “‘That’s cool, and I like it, but maybe it’s not jumping out, and it’s not making everyone jump around the room and [giving everyone] that feeling of ‘This is so exciting.’”

“I always say, ‘Let’s try it,’” Park says. “‘I don’t necessarily hear what you’re talking about, but let’s try it.’” Sometimes, hearing their idea come to life is enough to make the artist realize it isn’t a great fit. Park also occasionally asks the artist’s manager, significant other, or another trusted party to weigh in, hoping they’ll side with him. “But I am always honest. I’m like, ‘Yeah, I don’t think the idea works. If you like it, 100-percent do it. It’s not my vibe, but it’s your song.'”

And since the artist does have final say, the writers also need to know when to cut their losses. If the artist is hell-bent on certain subpar lyrics? “You’re going to go with whatever they’re going to like,” Capellaro says.

9. Songs sometimes get lost in the abyss.

Earlier this year, Stonestreet wrote Ariana Grande and Justin Bieber’s duet “Stuck with U,” which got released mere weeks later. “I just heard the demo of it last week, and it’s coming out Friday. I don’t understand what’s going on,” she thought at the time. “That was a freak thing. Usually you do have to wait a minute.” A minute could be a year—or never. “So many people have to say yes to the song for it to come out … All the label’s people, the artist’s team, your team.” Even after getting all those green lights, a single could still test poorly among advance radio reviewers and end up stalling indefinitely.

Sometimes, a record label neglects to send the finished product back to the songwriter. “I think some songs can go into a complete abyss where they just sit on a hard drive for years and years,” Stonestreet says.

10. Songwriters have mixed feelings about making music via Zoom.

Since songwriting often involves multiple people spending long hours in a small studio, the coronavirus pandemic threatened to upend the whole system. So songwriters went virtual. Some, like Park and Stonestreet, already had recording equipment at home; Capellaro, meanwhile, quickly invested in a mic, a monitor, cables, and all the other requisite gadgets. To shift the workflow online, they’ve had to more clearly define each person’s task for each song.

“I’m a vocalist, so I’m going to record vocals in my house, and I will send the stems to producer X, Y, or Z, have them tune them for me [and] put them into the rest of the track," Capellaro says. “I can have another guy master it, [and] we can always hop on a FaceTime or Zoom call to get it written and recorded.” This streamlined process has actually helped with productivity. “I have been writing more music since March than I was previously,” Capellaro says.

Making music via video chat tends to work better with fewer people, so Stonestreet has enjoyed the opportunity for more one-on-one sessions. When there are several people on the call, they cut down on confusion over who’s speaking (and singing) by thoroughly explaining each suggestion. “You really talk things through, which has been really nice,” she says. That said, the camaraderie born in the studio is hard to recreate on a computer screen, and songwriters are eager to experience that again. “I love Zoom, but I also really miss people in the room with me,” Stonestreet says.
