People are baffled to find out they've been burning candles wrong their whole lives

There's an art to avoiding the "memory ring" that makes a candle tunnel around the wick.

The "tunnel" that often forms around a wick isn't supposed to be there.

The evolution of candles from lighting necessity to scented ambience creator is kind of funny. For thousands of years, people relied on candles and oil lamps for light, but with the invention of the light bulb in 1879, fire was no longer needed for light. At that time, people were probably relieved to not have to set something on fire every time they wanted to see in the dark, and now here we are spending tons of money to do it just for funsies.

We love lighting candles for coziness and romance, relishing their warm, soft light as we shrink from the fluorescent bulb craze of the early 2000s. Many people use candles for adding scent to a room, and there are entire candle companies just for this purpose (Yankee Candles, anyone?). As of 2022, candles were an $11 billion business.

With their widespread use, you'd think we'd know a thing or two about candles, but as a thread on X makes clear, a whole bunch of us have been burning candles wrong our entire lives without knowing it.

A post from @kktweetshaha started the education session: "Just learned that my fiancé, who buys candles all the time and we literally always have candles burning, did not actually know how they work and blew out a medium first burn candle 30 minutes after I lit it when I wasn’t paying attention and ruined it."

Many people had no idea what she was talking about, so she explained.

"If a candle is not burned for long enough on first burn to melt edge to edge it will create a 'memory ring.' Once a candle has a memory ring, it will continue to tunnel and never burn all the way across."

"This is why you should not light a large candle at night, which is unlikely to burn all the way across before you need to blow out to go to bed. Allow at least one hour per inch of candle width," she went on.

So that's why candles always end up with a hole in the middle, making us think the candle companies are just running a scam to make us go through candles faster. Nope. It's user error, and many people were flabbergasted by this realization.

"This is the most useful information I’ve been given my entire adult life," wrote one person.

"This skill should be taught in schools," shared another. "The amount I’ve wasted on half burnt candles is outrageous, the amount of times I’ve used Algebra since leaving school = 0."

"When I worked at Pier 1 in the 90s I got to go to some candle workshop that taught us the correct way to use (and therefore sell) candles and that is probably some of the most useful knowledge I've carried in my head this long life," shared another.

Some people suggested wrapping aluminum foil around the rim of the candle to help recover a candle that's been tunneled or to speed the process of melting the wax across the entire candle. Other suggested melting the candle down in the oven to even it back out again. The original poster pointed out that sometimes candles aren't wicked properly. According to Lone Star Candle Supply, if a candle is more than 4 inches in diameter it may become necessary to have two wicks.

The candle posts also prompted a separate discussion about candles and indoor air quality and the volatile organic compounds that are released when they are burned. Some people equated burning candles with having a small engine running in your living room, though according to the Cleveland Clinic, there's scant evidence that the amount of toxins released by burning candles is actually hazardous to your health, especially if you use high quality candles in a well-ventilated area.

How do you know if a candle is "high quality"? First, check the wick for metal. Lead in wicks is not nearly as common as it used to be, but best not to risk it if you find metal in the wick. Second, choose soy, beeswax, palm or coconut wax candles instead of paraffin, which is petroleum-based product and more likely to put off soot and smoke particles. Everyone reacts differently to different amounts of particulates in the air, so if you find yourself getting headaches or respiratory symptoms when using candles, it's probably best to avoid them. But if you tolerate them, feel free to enjoy as recommended,—just make sure that first burn melts the wax all the way to the edges to avoid the dreaded tunneling.

Giant detective rats are helping catch exotic animal traffickers

Rats are an animal that people either love or hate, though it's safe to assume that most people would probably hate to come across the rodents in their home. But all rats aren't created equal, some were born to be...well, lab rats. While people may not like the critters, rats are extremely smart, which is why many of them end up in a lab but they're not always confined to the brightly lit sterile environment.

Sure some lab rats are destined to spend their time solving puzzles for treats, but some get to explore nature as part of their official duties. African giant pouched rats are getting a cute little vest, a backpack and a ball that signals their handlers to go work as rodent detectives. These furry guys are learning how to exercise their extreme sense of smell to help detect the scent of exotic animals being smuggled out of Africa.

Poaching and smuggling has been a problem that countries in Africa have been trying to address for a while. Poachers hunt animals like elephants for their ivory tusks, and rhinoceroses for their horns, often killing the animal in order to take their tusks and horns to sell them. But those aren't the only things getting smuggled off of the continent.

Pangolins, a small scaled mammal is one of the most trafficked mammals in the world according to APOPO, the Tanzanian nonprofit training the rats. In addition to the pangolins, elephant tusks and rhinoceros horns, the rats are also being trained to detect African Blackwood which is illegally logged.

The rats are trained using target training and reinforced with treats before being introduced to items that they should not be targeting as a method of "discrimination training." Essentially discrimination training is teaching the rats to not respond to things that aren't on the list. Now, while it would be adorable for the little vests the rats wear to say something like "detective" or "rat police," they don't. Their vests aren't for identification, they serve a practical nature.

The snug little vest the African giant rats wear have a little ball on them that looks like a bell you'd find on a cat collar. The rats are trained to pull on the ball when they detect a forbidden item. Once the ball is pulled, it sends a beeping sound to their handlers to alert them that something is being smuggled. Right now research is still in the trial stages, but the smart rats have shown great progress being able to identify the target items against over 150 non-target items like socks, or a watch.

Soon the detective rats will take on their biggest test yet, the airport in Dar es Salaam, Tanzania. Once the rats show they can correctly identify this exotic contraband in a large setting with lots of different competing smells, their job will move to the final stage–airport security. Well...sort of. The clever rats will be "operational" in the next couple of years in travel spaces like airports hoping to stop exotic traffickers in their tracks.

Who knew police dogs would face competition of giant rats the size of cats in the near future? There's plenty of room for all types of working furry creatures so long as one of the rats doesn't try to hitch a ride instead of reporting back to it's handlers.

A scared squirrel and a cheetah playing hide 'n seek.

For the past 9 years, the Comedy Wildlife Photography Awards has made people laugh with its competition, highlighting great nature photography that's too funny to find itself in National Geographic. This year is no different. The photography contest has announced 40 standalone images that have made the cut to compete for the top prizes after over 9,000 entries from 98 countries.

The top prize winner will receive a one-week safari with Alex Walker's Serian in Masai Mara. Among the entries are a cheetah playing hide-and-seek behind a tree, a squirrel stuck in a tree trunk and a frog caught in a bubble of his own making. The photographs are a lot of fun, but they also promote the message of conservation.

"We are thrilled to unveil the finalists for the Nikon Comedy Wildlife Awards, showcasing the incredible talent and creativity of photographers from all around the world," Stefan Maier, Nikon Europe's Senior General Manager of Marketing, said in a statement. "These images capture not only the humor and charm of wildlife but also highlight the importance of conservation in a way that resonates with people of all ages and from all different walks of life."


Each year, the competition supports a sustainable conservation organization and this year, Comedy Wildlife is delighted to be working with Whitley Fund for Nature (WFN), a UK charity that supports conservation leaders working in their home countries across the Global South.

Upworthy looked at the 40 finalists and chose 18 of our favorites. Check out the Comedy Wildlife Photography Awards website to see all 40 finalists and vote for the People's Choice Award.

"One of the 'lazy' mornings we have decided to stop by the pool with hippos while in Mana Pools NP. My idea was to try and catch fighting hippos, yet they all were quite peaceful. I have positioned on the bank, safely from the potential charge and waited. Some of them raised their heads in curiosity or when proximity to the other individuals was too close. Then I got this idea to catch the portrait with water plants decorating he head,It looked like the guy just got our of the hairdresser with a big smile on his face." — Arthur Stankiewicz

4. "The Contemplative Chimpanzee" by Arvind Mohandas (chimpanzee), Uganda

"In a kayak with my camera balanced precariously on the gunnel, I stayed very still while floating by this resting Sea Otter. It stayed relaxed (you can tell because it is still floating on its back) and kept on grooming its fur. With its peaceful face and upturned paws, it reminded me of a Guru meditating." — Charles Janson

6. "Saying My Prayers" by Christine Haines (sea otter), U.S.A

"These multi-ton giants fight to keep their harem of females. In the instant of the photo, the animal seems to be smiling. But the reality of the situation is that its expression of astonishment and smile is at the moment of fleeing quickly, because the dominant male was on his way to a bloody fight. It is better to preserve physical integrity... I better go." — Gabriel Rojo

10. "Laughing Out Loud" by Ingo Haman (seal), Germany

"This picture was taken in 2015 during my first visit to the Farne Islands (UK). The islands were full of puffins, kittywakes, shags, guillemots and razorbills, and I never before and since then have taken so many photos in such a short time. I think I really "saw" this image only later that day when I checked my haul." — Jörn Clausen

12. "Song of the Zeisel" by Kath Aggiss (European ground squirrel), Austria

"We were on safari in Kenya and happened upon this beautiful female who was looking for a mate. A group of topi were also keeping a pretty close eye her as she left messages for a potential partner on various trees. This shot makes me think that the cheetah is just about to shout out, "ready or not, here I come!" — Leslie McLeod

"

As we walked on the sands of the Namib Desert, a gecko suddenly appeared, emerging out of nowhere with a smile on its face. It positioned itself perfectly, posing for a portrait worthy of a National Geography cover. It seemed to say: 'Take my picture, I'm ready for my cover!'" — Michaela Bordoli

16. "Stuck Squirrel" by Milko Marchetti (squirrel), Italy

"An image that causes optical illusion, making it difficult for the viewer to tell which zebra is in front. Shot in Kenya, I stayed focused on these two as they started coming towards each other. I was expecting them to interact, nozzle or maybe fight, but they coincidentally got aligned in a way to cause this beautiful optical illusion." — Sarosh Lodhi

Artist creates amazing inflatable shower curtain to help save water

If you take long showers you’re in for a rude awakening.

Singing in the shower.

Are you the type of person who is always waiting on someone in the shower, or are you the one holding everyone up with your epic shower songs? Either way, Elisabeth Buecher has the perfect shower curtain for you. The London-based artist created an inflatable shower curtain that fills soft spikes with air if the shower is on too long. After four minutes of running water, a sensor on the tap triggers an inflator for the spikes, and the bather is immediately reminded that it's time to get out.

Buecher created the installation to raise awareness about water conservation.


"They aim at provoking a debate around water issues and making people more aware of their consumption," the artist said on her website.
