11 Sounds Today's Kids Have Probably Never Heard

Who knew that some noises would eventually become as extinct as the dodo? Depending on your age, you or your kids or grandchildren may have only heard some of the following sounds in old movies, if at all.

1. ROTARY DIAL TELEPHONE

The formerly familiar swooosh as the caller rotated the dial clockwise to the "finger stop" and then the click-click-click as the dial returned counter-clockwise to the start position is now a novelty application that you can install on your iPhones for nostalgic yuks. Adolescents waiting in line nearby will wonder what the heck that sound is.

2. MANUAL TYPEWRITER

Manual typewriters had an entire subset of unique sounds that made them immediately identifiable. The keys clacked loudly as they struck the paper, the carriage lifted up with a distinct clunk when the shift key was employed, and then there was the ping of the bell warning you that you were nearing the end of the line. That meant you had to lift your left hand from the keyboard and swipe at the carriage return lever, which caused a sort of ziiiiip noise as you pushed the carriage back to the starting position.

3. COFFEE PERCOLATOR

If steampunk had an aural definition, it would be the bloop-hissss of an old-school coffee percolator.

4. FLASH CUBE

The loud rapid-fire click-clack of an Instamatic camera equipped with a flash cube was a common background sound at any social gathering in the 1960s. It was a technological breakthrough to be able to snap off four—count 'em, four!—photos in rapid succession without having to pause and install a new flash bulb after every shot. Even back then, eco-minded individuals were concerned with the amount of waste flash cubes created, so it became a common holiday craft project to repurpose the used cubes into trendy Christmas tree ornaments.

5. TV CHANNEL SELECTOR

When announcers of yesteryear used to admonish viewers, "Don't touch that dial!", they were referring to the channel selector knobs found on TV sets. The standard TV dial went from 2 to 13, and you had to click on each number as you searched for one of the three channels that broadcast in your area. That meant a lot of clunk clunk-ing interspersed with the static-y sound of "snow" on the blank stations.

6. RECORD CHANGER

Record changers allowed you to stack a selection of albums or 45s (seven-inch singles) for your longer-term listening pleasure. Each record would make a soft slap sound as it dropped onto the turntable; a series of clicks followed as the remaining records adjusted into place and the tone arm swung over and lowered the needle into the outer grooves of the record. You'd hear the slightest scritch noise as the stylus settled just so into the vinyl and then (finally!) the music began.

7. GAS STATION DRIVEWAY BELL

Back in the days when all gas stations were full-service, the thin black pneumatic hose that snaked across the pavement was as familiar as the fuel pumps. When vehicles drove over the hose, a loud bell ding-dinged! inside the station, alerting the attendant that they had another customer. You can hear one hereand even order one for your home driveway if you really dislike your neighbors.

8. TV STATION SIGN-OFF

Before infomercials were invented, television stations actually went off the air for a few hours each night. Some of us TV-holics experienced physical withdrawal symptoms when we heard the announcer intone, "We now conclude our broadcast day..." around 2 a.m. or so. The format varied little from station to station across the country; first a few technical details were announced (broadcast frequency, physical address of the station, etc.), then a reading of "High Flight" followed by the National Anthem, and then the steady beeeeeeeeeeeeeep tone of the test pattern.

9. CASH REGISTER

Those chunka-chunka push buttons were clumsy, but veteran cashiers could check you out just as fast with these old-style machines as their modern counterparts do with today's scanners.

10. FILM PROJECTOR

One of the jobs of the classroom A/V squad captain was to run the film projector on movie days. The rapid tick-tick-tick of the sprockets really was that loud and usually accompanied by shouts of "Turn it up!" and, of course, "Focus!"

11. BROKEN RECORD

Remember when you'd beg mom over and over for something and she'd finally yell, "You sound like a broken record!"? She wasn't referring to pops or hisses, but the repetitive effect that happened when the needle got stuck and played the same few notes over and over and over again.

The World's 10 Most Expensive Cities

If you think San Francisco is pricey, you should see some of the other metropolises that appear in a new ranking of the 10 most expensive cities in the world. As The Real Deal reports, Singapore, Paris, and Hong Kong have been jointly named as the three cities with the highest cost of living in a new analysis by The Economist Intelligence Unit (EIU).

It was the first time in the history of the Intelligence Unit’s Worldwide Cost of Living report that three cities have tied for first place. Billing itself as a global business intelligence group, the EIU takes the prices of more than 400 items into consideration for its annual list, including food, clothing, household supplies, private school fees, and recreation.

Singapore's appearance on the list is no surprise, considering that it has been crowned the world’s most expensive city for the past five years in a row, and Paris has consistently made the top 10 since 2003. Hong Kong, meanwhile, rose three places in the newest ranking, while Osaka, Japan rose six places.

New York City and Los Angeles also made the top 10 list this year, tying with other cities for fourth and fifth place, respectively. This is partly due to exchange rates.

“A stronger U.S. dollar last year has meant that cities in the U.S. generally became more expensive globally, especially relative to last year’s ranking,” the report notes. “New York has moved up six places in the ranking this year, while Los Angeles has moved up four spots.”

5 Fast Facts About the Spring Equinox

The northern hemisphere has officially survived a long winter of Arctic temperatures, bomb cyclones, and ice tsunamis. Spring starts today, March 20, which means warmer weather and longer days are around the corner. To celebrate the spring equinox, hear are some facts about the event.

1. The spring equinox arrives at 5:58 p.m.

The first day of spring is today, but the spring equinox will only be here for a brief time. At 5:58 p.m. Eastern Time, the Sun will be perfectly in line with the equator, which results in both the northern and southern hemispheres receiving equal amounts of sunlight throughout the day. After the vernal equinox has passed, days will start to become shorter for the Southern Hemisphere and longer up north.

2. The Equinox isn't the only time you can balance an egg.

You may have heard the myth that you can balance on egg on its end during the vernal equinox, and you may have even tried the experiment in school. The idea is that the extra gravitational pull from the Sun when it's over the equator helps the egg stand up straight. While it is possible to balance an egg, the trick has nothing to do with the equinox: You can make an egg stand on its end by setting it on a rough surface any day of the year.

3. Not every place gets equal night and day.

The equal night and day split between the northern and southern hemispheres isn't distributed evenly across all parts of the world. Though every region gets approximately 12 hours of sunlight the day of the vernal equinox, some places get a little more (the day is 12 hours and 15 minute in Fairbanks, Alaska), and some get less (it's 12 hours and 6 minutes in Miami).

4. The name means Equal Night.

The word equinox literally translates to equal ("equi") and night ("nox") in Latin. The term vernal means "new and fresh," and comes from the Latin word vernus for "of spring."

5. The 2019 spring equinox coincides with a supermoon.

On March 20, the day the Sun lines up with equator, the Moon will reach the closest point to Earth in its orbit. The Moon will also be full, making it the third supermoon of 2019. A full moon last coincided with the first day of spring on March 20, 1981, and it the two events won't occur within 24 hours of each other again until 2030.
