The hydraulophone is a “woodwater” instrument: By fingering holes, the player stops the flow of of a fluid, but in this case the fluid is water. (The actual sound-producing mechanism can vary.)
Because the spray can obscure the finger holes, they’re sometimes marked in Braille, and the whole instrument can be built into a hot tub for use in cold weather.
Periodically Mount Etna emits rings of steam and ash. Not much is known as to how they form — perhaps a vent has assumed a particularly circular shape, so that emitted gas forms vortex rings — but they can be hundreds of feet wide.
Naturalist filmmaker Geoff Mackley captured these in June 2000, but they’ve recurred as recently as 2013.

I was surprised, and agreeably amused, with the following experiment. I covered a paper about four inches square with yellow, and with a pen filled with a blue colour wrote upon the middle of it the word BANKS in capitals, and sitting with my back to the sun, fixed my eyes for a minute exactly on the centre of the letter N in the middle of the word; after closing my eyes, and shading them somewhat with my hand, the word was distinctly seen in the spectrum in yellow letters on a blue field; and then, on opening my eyes on a yellowish wall at twenty feet distance, the magnified name of BANKS appeared written on the wall in golden characters.

To interest his students in the nomenclature of organic chemistry, Hofstra University chemist Dennis Ryan designed compounds in the shapes of little figures. Shown here are oldmacdenynenynol, cowenynenynol, and turkenynenynol; he also designed a goose, a snake, a giraffe, and a duck.

These spiral stairs, in the Pio-Clementino Museum in Vatican City, take the form of a double helix — there are two heads and two feet, so that one party can descend while another ascends and the two will never meet.
Designed in 1932 by Giuseppe Momo, the stairs are modeled on a much earlier stair by Donato Bramante, which occupies a square tower in the Belvedere palace of Pope Innocent VIII. Like the museum stair, it allows traffic to travel in both directions without impediment.
In 1952, New Zealander Tom Neale set out to establish a solitary life for himself on a remote island in the South Pacific. In all he would spend 17 years there, building a fulfilling life fending entirely for himself. In this week’s episode of the Futility Closet podcast we’ll describe Neale’s adventures on the island and his impressions of an isolated existence.
We’ll also revisit Scunthorpe and puzzle over a boat’s odd behavior.
Minutes of a borough council meeting, quoted by Robert Graves and Alan Hodge in The Reader Over Your Shoulder, 1943:
Councillor Trafford took exception to the proposed notice at the entrance of South Park: “No dogs must be brought to this Park except on a lead.” He pointed out that this order would not prevent an owner from releasing his pets, or pet, from a lead when once safely inside the park.
The Chairman (Colonel Vine): What alternative wording would you propose, Councillor?
Councillor Trafford: “Dogs are not allowed in this Park without leads.”
Councillor Hogg: Mr. Chairman, I object. The order should be addressed to the owners, not to the dogs.
Councillor Trafford: That is a nice point. Very well then: “Owners of dogs are not allowed in this Park unless they keep them on leads.”
Councillor Hogg: Mr. Chairman, I object. Strictly speaking, this would prevent me as a dog-owner from leaving my dog in the back-garden at home and walking with Mrs. Hogg across the Park.
Councillor Trafford: Mr. Chairman, I suggest that our legalistic friend be asked to redraft the notice himself.
Councillor Hogg: Mr. Chairman, since Councillor Trafford finds it so difficult to improve on my original wording, I accept. “Nobody without his dog on a lead is allowed in this Park.”
Councillor Trafford: Mr. Chairman, I object. Strictly speaking, this notice would prevent me, as a citizen who owns no dog, from walking in the Park without first acquiring one.
Councillor Hogg (with some warmth): Very simply, then: “Dogs must be led in this Park.”
Councillor Trafford: Mr. Chairman, I object: this reads as if it were a general injunction to the Borough to lead their dogs into the Park.
Councillor Hogg interposed a remark for which he was called to order; upon his withdrawing it, it was directed to be expunged from the Minutes.
The Chairman: Councillor Trafford, Councillor Hogg has had three tries; you have had only two …
Councillor Trafford: “All dogs must be kept on leads in this Park.”
The Chairman: I see Councillor Hogg rising quite rightly to raise another objection. May I anticipate him with another amendment: “All dogs in this Park must be kept on the lead.”
This draft was put to the vote and carried unanimously, with two abstentions.
Every Christmas for more than 30 years, someone has decorated this 20-foot juniper tree in the median of Interstate 17 about 55 miles north of downtown Phoenix, Arizona.
The decorations, the same ones every year, go up before Thanksgiving, and they’re taken down after New Year’s Day.
“I know who started it, but I’m not going to go into that,” former transportation department employee Tom Foster told the Arizona Daily Courier in 2009. “I heard there’s some elves that got to looking at how bleak we were … and people weren’t celebrating Christmas very well. They thought [the decorations] are a good way to brighten the drive between here and Phoenix.”
“But don’t stop on the road. That’s not what Santa wants.”
Attractive people are more likely to be rated as having higher intelligence, greater loyalty, more dependability, and stronger leadership skills than others, regardless of their actual qualities. Teachers are more likely to rate attractive students as diligent, engaged, hard-working, and intelligent, and students rate attractive teachers as more likable and appealing. Attractive job applicants are more likely to be rated as qualified and competent, regardless of their actual experience or skills. Once hired, attractive employees get more opportunities and higher salaries and are more likely to be rated as more knowledgeable, enthusiastic, and effective. Attractive spokespeople bring greater trust and better evaluations to a product, attractive political candidates are overwhelmingly more likely to be elected, and jurors are less likely to believe that an attractive person is guilty of a crime.
In the United States, physically attractive people are thought to be smarter, warmer, happier, healthier, more sociable, less lonely, and less anxious than others. They’re less likely to be identified as psychopaths or mentally unbalanced, and they’re thought to have better prognoses in the face of physical or psychological problems.
These expectations can fulfill themselves. For example, attractive people haven’t actually been found to be more intelligent than unattractive people, but they do tend to achieve more: “Since attractive people are perceived to have superior intelligence, they are likely given more opportunities, more support, and more encouragement, all prerequisites for short- and long-term success.”
