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.

10 Surprising Uses for Coffee That Don’t Involve Drinking It

For the people who manage to make it through each day without tossing back cup after cup of Mother Nature’s deliciously bitter bean water, coffee might seem totally useless. And even if you do run on java, you may not realize how useful those leftover grounds can be. From fertilizing your garden to making boxed brownies taste homemade, here are 10 ways to make the most of coffee without drinking a drop.

1. Fix furniture scuffs and scratches.

You can claim the scuffs are what give your coffee table its character, but would you say the same if you knew how easy it was to get rid of them? This DIY stain from PopSugar calls for your leftover coffee grounds, 1/4 cup of warm water, and 1/4 cup of vinegar; shake the mixture, let it sit for at least an hour, and then rub it into furniture blemishes with a rag (you may need to apply a few layers for darker shades of wood).

2. Make an air freshener for just about anywhere.

Funnel some dried coffee grounds into an old pair of pantyhose and tie it off at the top for a simple air freshener that will neutralize funky smells in your fridge, car, gym bag, or any other place that has you wrinkling your nose.

3. Eliminate lingering odors on your hands.

The natural deodorizing property of coffee can help when you want to get a stubborn stench off your hands, too. Mix a pinch of coffee grounds into your soap and scrub until your fingers no longer smell like onions, garlic, or whatever else you’ve been chopping.

4. Exfoliate your face.

Finely ground coffee is gentle enough to use as a facial exfoliant, and it’s also packed with antioxidants that are great for your skin. This recipe from Nyakio Grieco, founder of the skincare line Nyakio Beauty, is a mixture of coffee grounds, brown sugar, avocado oil, and coconut oil, with additional options to modify it based on your skin type.

5. Fertilize your garden.

According to Healthline, coffee grounds release nitrogen, potassium, magnesium, and other minerals that stimulate plant growth—and they also repel insects that might damage those plants. You can sprinkle coffee grounds directly on the soil, or you can add them to your compost and work it into your garden once everything’s decomposed.

6. Clean your fireplace.

Cleaning out your fireplace can fill the air with ash, making it a pretty miserable task even for people without respiratory issues. Sprinkling a thin layer of coffee grounds on top first will prevent the ash from rising when you sweep it up.

7. Enrich your baked goods.

Coffee-flavored cakes, muffins, and other desserts are delicious to anyone who loves a good cup of Joe, but coffee can also take certain baked goods to the next level without making them taste like moist, fluffy espresso beans. According to Lifehacker, this works best for chocolate desserts like brownies and cakes, especially if you’re using a box mix. Just substitute brewed coffee for whatever amount of water the recipe calls for; the coffee will add richness and complexity to the chocolate flavor, and your guests will think you made the dessert from scratch.

8. Fill a homemade pincushion.

Filling your homemade pincushion with dried coffee grounds will keep all your pins in one place and make your sewing box smell delightful. Here are step-by-step instructions to create your own from the Queen Bean Coffee Company blog.

9. Enhance your fish bait.

There’s not much scientific evidence that coffee does indeed attract more fish, but plenty of seasoned fishers vouch for its efficacy—there are even coffee-scented bait products on the market. Gone Outdoors recommends letting worms wriggle around in coffee grounds for a while before putting them on the hook.

10. Dye some fabric.

You’re one large pot of coffee away from nailing the natural prairie look. Dyeing your clothes fifty shades of tan really just entails soaking them in brewed coffee for varying lengths of time, but these additional tips from The Spruce Crafts can help you get your desired results. (Even if you’re not interested in revolutionizing your wardrobe, using coffee as dye can come in handy if you need to dirty an item for a Halloween costume or upcycle an already-stained kitchen towel.)
