In 1994, inventor Albert Cohen saw a peculiar opportunity:

During a televised sporting event, a ‘high five’ is commonly shared between fans to express the joy and excitement of a touchdown, home run, game-winning basket, birdie or other positive occurrence. Unfortunately, as known in the art, a ‘high five’ requires the mutual hand slapping of two participants, wherein a first participant slaps an upraised hand against the elevated hand of a second participant. As such, a solitary fan is unable to perform a ‘high five’ to express excitement during a televised sporting event.

His “apparatus for simulating a high five” can be mounted on a table, wall, or floor — and it even promotes physical fitness: “When the hand-arm configuration is mounted at a sufficient height above the normal reach of a user, the user must jump upwards to strike the simulated hand, thereby simulating many of the jumping drills commonly practiced by basketball players. As such, the leg strength and coordination of a user may be improved through the practice of the present invention.”

In 1783, Benjamin Franklin watched a balloon carry a man into the sky over Paris.

“What good is a balloon?” scoffed a man in the crowd.

Franklin responded, “What good is a newborn baby?”

‘Overhead’ is a familiar technical term in newspaper work. It describes a report flashed to a newspaper directly by commercial telegraph instead of through the regular channels of a wire service. For instance: on Decoration Day in the town of Walsenburg, Colo., 50 mi. south of Pueblo, Editor John B. Kirkpatrick of the World & Independent wired Associated Press in Denver that he wanted coverage of the Indianapolis automobile races. Presently AP wired its reply: WILL OVERHEAD WINNER OF INDIANAPOLIS RACES. Editor Kirkpatrick jumped with excitement. An hour later the World & Independent’s 1,750 readers puzzled over an 8-column streamer:

OVERHEAD WINS INDIANAPOLIS RACE

The story, as edited by Editor Kirkpatrick, began:

INDIANAPOLIS, Ind. (AP) — Will Overhead won the Indianapolis Memorial Day race today. At the 250 mile post Babe Stapp was leading the string of roaring cars, but gave way to Overhead on the last half of the 500 mile grind.

In 1916, inventor Hugh Huffman offered “a more efficient form of scarecrow,” a faux cat mounted on a wind vane and fitted with bells. “The action of the wind will give various motions to the figure which will simulate the lifelike movements of the animal.”

If it worked then, it ought to work now.

“What can you conceive more silly and extravagant than to suppose a man racking his brains, and studying night and day how to fly?” So wrote the English cleric William Law in 1728, and in the late 19th century inventors were still struggling to reach the heavens.

Watson Quinby’s 1872 “flying apparatus,” above, was designed to permit the user to grope through the air with actions “resembling those of swimming in water.”

In 1889, Jasper Spalding was emulating a bird rather than a bat with a feathered flying machine designed to be suspended from a balloon (below).

Neither got off the ground … but within one lifetime we had reached the moon.

In the 19th century manuals such as Gunn’s Domestic Medicine promised that “any man, unless he be an idiot or an absolute fool,” could perform an amputation. But Pennsylvania surgeon George Griswold had found that “persons unskilful in the use of the saw, and even the most experienced, will find it difficult to hold the bone firmly,” increasing both the patient’s pain and length of the operation. He invented this “amputator’s assistant” to hold a limb steady while a surgeon saws through it.

He patented it in 1854, only seven years before the Civil War. I haven’t been able to learn how widely it was used.

In The Innocents Abroad, Mark Twain describes a remarkable automaton that he encountered at the Exposition Universelle in Paris in 1867:

I watched a silver swan, which had a living grace about his movements, and a living intelligence in his eyes–watched him swimming about as comfortably and as unconcernedly as if he had been born in a morass instead of a jeweler’s shop–watched him seize a silver fish from under the water and hold up his head and go through all the customary and elaborate motions of swallowing it.

The swan still exists, now on display at England’s Barnard Castle. As a music box plays, the life-size creature preens, searches a flowing “stream” of rotating glass rods, spies a fish, and catches and swallows it. No one knows who designed it, but it’s certainly more than two centuries old — it’s described in a 1773 Act of Parliament.

In 1900, evidently tired of initiating pledges by hand, Edmund and Ulysses de Moulin decided to automate the process.

With their “initiating device,” the applicant is blindfolded, placed in position, and told to pull the handles to test his strength. When he does so, the paddle spanks him and an electric shock passes through his arms, “making the sensation rather unique.”

You could turn this into a regular assembly line — or, using multiple machines, humiliate an entire freshman class at once.

At Southsea, Portsmouth, and other places off which our warships are accustomed to anchor, many of the better-educated servant-maids with sailor sweethearts have learnt to be such experts in the way of heliographing that, with ordinary small mirrors, they frequently flash messages to the men on the ships. A naval officer told the present writer that he had often, when on deck, been both amused and surprised at the accuracy with which some of these girls used this form of signalling out of pure fun.

Well! It seems you have gotten so wrapped up in piano practice that you have forgotten about KILLER BEES!

Don’t look to me for help; I’m hiding in the cellar. Happily Virginia L. Butler has got you covered — in 1996 she invented a 6×3 bag of flexible, transparent, and sting-resistant plastic, complete with a mesh-covered aperture through which you can jeer at your frustrated attackers.

“In use, one can quickly unfold the present invention when the sound of a swarm is initially heard and enter the protective chamber before the bees actually approach. Even if one or two bees enter the enclosure during the process, the number of stings and proportionate danger will be greatly reduced.”

Conveniently, the bag can be folded and carried in a lightweight pouch that “fits easily into a backpack, purse, picnic basket, or pocket.” You can keep it near the piano.
