The Explainer General
Since he was a boy, John Collins has been fascinated by paper airplanes. Who isn’t? Most of us have folded the familiar dart-shaped classroom airplane. Good fun. And it’s science.
Big and small aircraft depend on the same four principles: weight (of the craft), drag (wind resistance over the craft), lift (upward force from air passing over the craft’s flight surfaces), and thrust (what pushes the craft). A 747 Jumbo Jet and a paper airplane depend on the same forces.
Collins wanted to fold this aeroscience into paper. But how to build (fold) complex principles into something so small?
He found the ancient Japanese art of origami and used its sculptural tricks. He created paper aircraft that do astonishing things. One comes back in a horizontal circle, like a boomerang. Another flies up, turns over and comes back vertically. One actually flaps its wings as it glides slowly. To John, they’re all working science experiments: every flight leads to some knowledge and to new ideas for tweaking the aircraft so it flies better.
John Collins became “The Paper Airplane Guy.” He believes that scientific research happens everywhere, every day. He says, “It doesn’t take computers, lab coats, microscopes and the like. It takes a hunger to know. Science is just the structured way we find stuff out. The science you can do with a simple sheet of paper is no less important than what can be done with an electron microscope.”
On February 26, 2012, John and Joe Ayoob stood in a big, windless aircraft hangar with John’s best-so-far flyer, Suzanne. (He named it after his wife.) Joe was a professional football quarterback who learned to throw Suzanne hard but steady, not like a football but like a delicate piece of origami. Joe threw Suzanne up, up, and it dived down to fly – really fly – 226 feet and 10 inches, the Guinness World Record for distance thrown.
John wanted paper airplanes to welcome young people into science. He started a National Paper Airplane Contest called the Kickstarter Project with a big prize for anyone who throws Suzanne farther than Joe. Or you could throw your own better, more aeronautically elegant paper airplane. It was a simple, scientific task. Every paper airplane and every flight would be a new experiment, just as important as the Wright Brothers’ Kittyhawk flight. Science isn’t just geeks and labs; we’re all part of it. The project didn’t get support and ended. John would like to direct people to www.TheNationalPaperAirplaneContest.com. Air and Science museums across the country will be hosting events. The museums get three Fly for Fun Days; STEM education days that teach basic flight concepts and skills for the national contest.

No one wants to mess with someone who is super strong! Even if you’re undersized, especially if you’re undersized, you’ve got to try the two tricks in this Minute .
Here’s the first challenge: Bet another person can’t remove your hand from the top of your head. The challenge-taker must try to remove your hand according to your rules. Otherwise, it’s cheating. Sit on the floor. Place your hand with your fingers spread apart firmly on the top of your head. Have your friend grasp your lower arm next to your elbow. Now let him/her pull upward, trying to lift your hand from the top of your head.
Chances are excellent that you’ll be lifted off the ground before your palm parts from its perch.
Why is this so? If you’ve studied simple machines you may have learned about a mechanical advantage. That’s how a simple machine such as a lever can multiply your strength or speed. In this case, you’re putting your friend at a mechanical disadvantage. Your arm is a lever. In order to move your hand from the top of your head, you need an upward force near your hand. If that force is delivered as far away from your hand as possible, it loses its power. It’s easy to remove your hand if you deliver an upward force near your wrist. But at your elbow? No way! Got it?
Here’s another trick with the secret sauce of physics. Bet you can keep ten people from shoving you into a wall. Place your hands against a wall with your fingers spread and your arms outstretched. Have ten people line up behind you, hands on the shoulders of the person in front of them. At the count of three, have everyone push on the person in front of them as hard as they can. I mean, really lean in.
You, hero of the day, can hold them all off and not bend your elbows.
Why? Actually, each person absorbs the force of the person behind them so that you are not experiencing the cumulative force of ten people, only the force of the person directly behind you. So pick someone smaller than you to be that first person. If you’re not super strong, you can still be super smart.
If you don’t want to try this yourself, look at my videos of other people doing the challenges. Maybe you’ll change your mind.

If you go to the nation’s official World War I Museum, in Kansas City, Missouri, you might see a paving stone that reads:
And you might say, “Huh?” So here’s his story, just for you to know:
In 1917 Connecticut, a terrier puppy strayed onto a Yale University field, where soldiers were training to fight in World War I. There is MUCH to say about WORLD-CHANGING WWI. For instance, it began late summer, 1914 Europe. On April 6, 1917, the US joined 23 other Allies, such as Great Britain, in their fight against the Central Powers: Germany, Austria-Hungary, Bulgaria, and the Ottoman Empire.
The puppy quickly learned army life and lots of tricks. Private John R. Conroy adopted the pup he named “Stubby” and tried to sneak him overseas. When Stubby was discovered, he charmed the angry officer by raising his right paw and saluting him!
Stubby and Conroy served in France, by Germany’s border, where millions of soldiers fought one another along a 450-mile battle line. This was WWI’s deadly Western Front. Soon, Stubby was nearly killed by poison gas. Because the attack sensitized his nose, he became a barking, life-saving, put-your-mask-on early warning device! With his sensitive ears, Stubby could hear a lost or injured man then go help him. Once, he heard a suspicious-sounding man. Stubby chased and caught a German SPY by the seat of his pants! For this, SERGEANT STUBBY, the official mascot of the 26th Division of the American Expeditionary Forces, became the first dog ever promoted by the US Armed Forces.
WWI ended when the victorious Allies made their enemies agree to an ARMISTICE: As of 11 A.M. November 11, 1918, the fighting would STOP.
For his brave actions, battle-scarred Sgt. Stubby was WWI’s most decorated dog. Even the top US officer, General John J. Pershing himself, gave him a medal! How did Stubby wear his awards? They were attached to his soft leather blanket, made by grateful Frenchwomen. Stubby met three Presidents (Wilson, Harding, and Coolidge). In America, Stubby was in LOTS of victory parades and he appeared at Georgetown University football games, too, as their team mascot. (Conroy studied law there.)
Faithful Sgt. Stubby was about ten when he passed away in Conroy’s arms on March 16, 1926. His obituary was printed in the New York Times. Still, you can visit Stubby (his preserved remains anyway), in Washington, DC, at the Smithsonian Museum of American History
Ghosts of the Civil War is author/illustrator Cheryl Harness's popular sequel to her Ghosts of the White House. Here she takes readers on a fantastical, factual time travel journey through the Americans' tragic war between themselves.
Bessie Coleman, better known as Queen Bess, was America’s first black woman pilot. Born in Texas in 1892, into a world of extreme poverty and deepening racial discrimination, her dream to “amount to something one day” was fought against overwhelming odds. Working as a manicurist in a Chicago barbershop, she read about World War I pilots. She decided that she wanted to become a pilot. But she was met with the reaction: “You, a Negro and a woman—you must be joking.”
Undeterred, Bessie sought the advice of a valued customer in the barbershop. “Go to France,” he said. “The French are much more accepting of both women and blacks— but first learn the language.”
That same day, Bessie began taking French lessons. A few months later, she sailed for France, and signed up with an aviation school. Her training included everything from banked turns and looping-the-loop to airplane maintenance. In 1921, she became the first black woman to earn a pilot’s license.
Back in the U.S., an African-American woman pilot was big news. Thunderous applause and a rousing rendition of “The Star-Spangled Banner” greeted Bessie at her first airshow in New York. Memphis and Chicago followed. Bessie’s future never looked brighter. She managed to buy an old Curtis Jenny, a favorite plane among barnstormers. She was heading for a performance in Los Angeles, when the engine stalled; she crashed onto the street below, was knocked unconscious, broke one leg, and fractured several ribs.
Distraught over having disappointed her fans, she sent a telegram to the local newspaper: AS SOON AS I CAN WALK I’M GOING TO FLY! Seven months later, she was back in a borrowed plane, performing to upbeat crowds in Ohio, Texas, and Florida.
Bessie loved flying and accepted its risks, but her real ambition was to open a flight school. Sadly, she didn’t live to see her dream realized. In 1926, her old, run-down plane went into a spin. Bessie was thrown out of her seat, and fell to her death.
At her funeral, thousands paid their respects to the brave young aviator. With her pluck and determination, Bessie Coleman had set an example for many black people.
Shortly thereafter, the Bessie Coleman Aero Club in Los Angeles became a reality, introducing young blacks to the world of aviation. Among those inspired by Bessie was Dr. Mae Jemison, the first woman African-American astronaut.
