10 Durable Facts About Duct Tape

Duct tape can be found in the tool box of any self-respecting handyman, but the versatile product's potential extends far beyond home repairs. From its origins in the military to its popularity with NASA, here are some surprising facts about the reliable adhesive.

1. IT WAS INVENTED TO MEET A MILITARY NEED.

Before the invention of duct tape, packages of ammunition that were sent to the military were sealed with wax to keep their contents waterproof. The cardboard flaps were held shut with a strip of paper tape with a tab hanging loose that would allow soldiers to rip open the boxes in a hurry. Because this type of tape wasn’t very strong, the tabs would often tear off in their hands and leave soldiers struggling to free their ammunition in the heat of battle. 

Hoping to solve the problem, Vesta Stoudt, a mother of two Navy sailors and a worker at the Green River Ordnance Plant in Illinois, wrote to President Franklin Roosevelt with an idea: 

"I suggested we use a strong cloth tape to close seams, and make tab of same … I have two sons out there some where, one in the Pacific Island the other one with the Atlantic Fleet. You have sons in the service also.  We can’t let them down by giving them a box of cartridges that takes a minute or more to open, the enemy taking their lives, that could have been saved."

Roosevelt passed along the letter to the War Production Board in Washington, D.C., who contacted Johnson & Johnson to develop the product. The result was a strong, waterproof tape that soldiers could still tear apart with their hands in a pinch.

2. THE NAME "DUCK TAPE" CAME FIRST.

Since its origins, the tape has consisted of three major components: a bottom layer of glue, mesh fabric, and a polyethylene plastic coating on top to keep it water-resistant. According to Johnson & Johnson, soldiers nicknamed the material "duck tape" in reference to its ability to repel moisture "like water off a duck’s back."

3. IT OWES ITS STICKINESS TO PHYSICS.

While many adhesives, like Elmer’s glue, need to undergo a physical change in order to stick to something, duct tape works a little differently. Its stickiness is created by a pressure-sensitive adhesive, or PSA, which is a soft polymer blend that employs van der Waals forces to attract two surfaces. These intermolecular forces are weak on their own, but with enough of them, they are capable of supporting very heavy loads (this is the same principle that allows geckos to stick to walls).

"Other adhesives, like glues and epoxies, are liquid when you apply them, but they react chemically and harden," Costantino Creton, a materials scientist at the School of Industrial Physics and Chemistry in Paris, told Chemical and Engineering News. "PSAs have no chemical reaction. They don't change at all. They are in the solid state when you apply them, and they stick in their solid state." This makes duct tape the perfect option if you’re looking for a super strong adhesive that's also removable.

4. YOU CAN’T USE IT IN DUCTS.

Following World War II, duct tape began to catch on in the U.S. as a handy tool for home construction. People were using it to hold metal air ducts together, so the company rebranded the product as "duct tape" and updated it with a matching silver color made from powdered aluminum.

Today, its namesake usage is one of the few things that duct tape isn’t recommended for. Lawrence Berkeley National Laboratory conducted tests in 1998 to see how well different types of tape performed at sealing ducts, and, compared to the other products, duct tape was the clear loser. "Of all the things we tested, only duct tape failed. It failed reliably and often quite catastrophically," Max Sherman, one of the researchers, told Berkeley Lab Research News. Using duct tape on actual ductwork is now considered a code violation in many buildings.

5. DUCT TAPE HELPED SAVE APOLLO 13. 

Following an explosion aboard the ship’s service module, the three members of the Apollo 13 crew transferred to a lunar module designed to hold two people for 36 hours. They had to find a way to last more than twice that long, and the biggest threat to their survival was the carbon dioxide being created by their own bodies. While they had plenty of square carbon dioxide filters on board, they were incompatible with the lunar module’s round holes. Engineers at NASA devised a solution that involved using cardboard, plastic bags, space suit components, and duct tape that was kept on board to create an adapter that would filter out carbon dioxide. This hack ultimately saved the astronauts’ lives.

This wasn’t the only time duct tape proved to be useful in outer space. The tape has been stowed on board every NASA mission since the early Gemini era. Some of its handy applications include making emergency rover repairs, fixing leaky pipes, and keeping items secure in zero gravity.

6. IT HAS BEEN USED TO PREVENT INFECTION ...

Hospital-acquired infections account for 99,000 preventable deaths in the U.S. each year. In order to safely fight infection while saving doctors time and effort, the Trinity Medical Center system of hospitals in the Midwest came up with a rather simple solution. They used duct tape to mark 3-foot-square “safe zones” extending from the doorway into a patient's room. This allowed physicians to casually converse with their patients without having to change into full sterile gear every time they wanted to check in. Research shows that the duct tape idea saved the hospital system $110,000 a year and 2700 hours of staff time.

7. … AND A WHOLE LOT MORE.

Mythbusters has devoted three entire episodes to exploring some of duct tape’s most extreme applications. The team was able to successfully use duct tape to patch a damaged airplane fuselage, construct a functioning cannon, build a usable bridge, and lift a 5000-pound car. Of the 18 myths they tested, only one was busted (turns out you can’t use duct tape to barricade a car driving at 60 mph).

8. THERE’S AN ANNUAL DUCT TAPE FESTIVAL.

Since 2005, Avon, Ohio has hosted an annual duct tape festival dedicated to celebrating "duct tape, its enthusiasts, and its wacky and fun uses." The event features duct tape sculptures, a duct tape fashion show, and a parade of giant floats constructed using duct tape. 

9. THERE’S DUCT TAPE TO SUIT EVERY NEED.

Specialty varieties of the product include outdoor duct tape, double-sided duct tape, glow-in-the-dark duct tape, and nuclear-grade duct tape (the latter is certified for use in nuclear power plants).

10. WEARING DUCT TAPE TO PROM COULD EARN YOU A SCHOLARSHIP.

Duck brand duct tape offers a rather unusual scholarship to high schoolers who are willing to get creative with their product. Every prom season, they call upon students to design and create their own suits and dresses for the big day using duct tape. The winning couple of the "Stuck at Prom" competition is awarded a $10,000 scholarship each along with an additional $5000 for their high school.

11 Songs Inspired by Literature

Devo and Thomas Pynchon. Mick Jagger and Charles Baudelaire. Though they seem like rather unlikely pairings, many great rock songs have been the result of a lyricist finding inspiration in the pages of a book. These are just the tip of the iceberg.

1. “Pigs (Three Different Ones)" // Pink Floyd

The Novel: Animal Farm // George Orwell

Pink Floyd felt so strongly about Orwell’s barnyard take on revolution that they made a mascot from the book’s dictator pigs. The first incarnation of the famous Pink Floyd pigs popped up in 1976 for the photo shoot for 1977’s Animals album, which is based loosely around Animal Farm themes. "Pigs (Three Different Ones)" is about people in society with wealth and power.

2. “My Ántonia” // Emmylou Harris

The Novel: My Ántonia // Willa Cather

It's somehow not surprising that Emmylou Harris is a fan of Willa Cather. Written from the perspective of Jim, the man who loved Cather’s title character in My Ántonia, the song was actually composed several years prior to its release on the 2000 album Red Dirt Girl. Harris hung on to it for a while, not sure what she wanted to do with it since she had written it from a man’s perspective.

“One day I got the idea to make it a conversation and the song just seemed to write itself. Well, then I had to pick a 'leading man,'" Harris said when the album was released. "I had just done a show with Dave Matthews and I loved the way we sounded together. And he did a simply beautiful job.”

3. “Whip It” // Devo

The Novel: Gravity’s Rainbow // Thomas Pynchon

Devo's singer/bassist Jerry Casale told the website Songfacts that his band's monster hit was based on Pynchon's postmodern novel:

"'Whip It,' like many Devo songs, had a long gestation, a long process. The lyrics were written by me as an imitation of Thomas Pynchon's parodies in his book Gravity's Rainbow. He had parodied limericks and poems of kind of all-American, obsessive, cult of personality ideas like Horatio Alger and 'You're #1, there's nobody else like you' kind of poems that were very funny and very clever. I thought, 'I'd like to do one like Thomas Pynchon,' so I wrote down 'Whip It' one night."

4. “Wuthering Heights” // Kate Bush

The Novel: Wuthering Heights // Emily Brontë

An 18-year-old Kate Bush wrote her breakout song after seeing just 10 minutes of Wuthering Heights on TV in 1977. In 1980, she told an interviewer on the Canadian show Profiles in Rock that she was inspired by the novel's heroine:

“I am sure one of the reasons it stuck so heavily in my mind was because of the spirit of Cathy, and as a child I was called Cathy. It later changed to Kate. It was just a matter of exaggerating all my bad areas, because she's a really vile person, she's just so headstrong and passionate and ... crazy, you know?”

5. “The Ghost of Tom Joad” // Bruce Springsteen

The Novel: The Grapes of Wrath // John Steinbeck

Springsteen was inspired by John Ford’s big-screen adaptation of John Steinbeck’s Great Depression saga. “The Ghost of Tom Joad” is a 1990s version of The Grapes of Wrath, meant to serve as a reminder that modern times are just as difficult for some. Rage Against the Machine covered the song in 1997.

6. “Sympathy for the Devil” // The Rolling Stones

The Novel: The Master and Margarita // Mikhail Bulgakov

In 1968, Mick Jagger’s then-girlfriend, Marianne Faithfull, passed along a little book she thought he might enjoy. Jagger ended up writing “Sympathy for the Devil” after reading the novel, which starts when Satan, disguised as a professor, walks up and introduces himself to a pair of men discussing Jesus.

Jagger later suggested that some of the lyrics may have been inspired by the works of Charles Baudelaire as well, which makes “Sympathy” the product of a pretty well-read rock star.

7. “Holden Caulfield” // Guns N' Roses

The Novel: The Catcher in the Rye // J.D. Salinger

Guns n' Roses' much-awaited 2008 album Chinese Democracy contained a song called “The Catcher in the Rye” after the J.D. Salinger classic. Some surmised that the song is really about another culture-changing event that Holden Caulfield was involved in: the assassination of John Lennon in 1980. Lennon’s murderer was carrying a copy of the book when he pulled the trigger.

8. “Tales of Brave Ulysses” // Cream

The Poem: The Odyssey // Homer

Even Eric Clapton couldn’t resist the Sirens from The Odyssey; this classic Cream song references the mythological enticing beauties (Clapton sure knew his share of those). Though it’s Clapton singing, the lyrics were written by Martin Sharp, who had just returned from vacation in Ibiza and was inspired by the exotic scenery—beaches and women alike, presumably.

9. “Breathe” // U2

The Novel: Ulysses // James Joyce

Speaking of The Odyssey, it’s no surprise that The Edge and Bono would want to pay homage to their fellow Irishman James Joyce by setting “Breathe” on June 16. That’s the day Leopold Bloom embarks throughout the pages of Joyce’s Ulysses, and it’s also the day that Joyce fans everywhere honor his work by celebrating Bloomsday.

10. “Ramble On” // Led Zeppelin

The Novel: The Lord of the Rings // J.R.R. Tolkien

If you’ve ever listened to the lyrics of “Ramble On,” this is not going to come as a surprise to you. For example:

“'Twas in the darkest depths of Mordor
I met a girl so fair.
But Gollum, and the evil one crept up
And slipped away with her.”

11. “Scentless Apprentice” // Nirvana

The Novel: Perfume: The Story of a Murderer // Patrick Süskind

This horror book was a modest hit thanks in part to Kurt Cobain, who frequently mentioned that it was one of his favorite reads. He liked it so much, in fact, he wrote a song about it and put it on his band's 1993 album In Utero. The book is about a man who kills young women and captures their scents in order to make the perfect perfume. I won’t spoil the ending for you—and neither does “Scentless Apprentice.”
