40 Times People Had No Idea What They Were Looking At, But The Internet Knew What It Was Right Away (New Pics)
The last time we wrote an article about the subreddit "What is this thing?", it had 894,000 members. Now, the number has grown to 1.8 million. No wonder -- it delivers. People keep going to the community with photos of possessions they need identifying, and they keep getting answers, too.
From the roof plate of a drum fish to a fancy sugar cube holder, these Internet detectives don't shy away from any case. "About 75-85% of all the items posted to this subreddit are solved, and out of those about 50-60% are solved within the first 30 minutes of the post going live," a moderator of the subreddit told Bored Panda. "The average time of solving what an item is around 20-30 minutes, and about 15-20% of the posts made here don't go live at all, because the moderation team has solved it through modmail, or by commenting on the post before it goes live due to the sheer amount of different things the moderators have seen."

I Found This Blue Disc In A Packet Of Sour Cream Crisps. Its Has The Words "Ferrous 25mm Bst, Cert Number 213026b" On It. What Is This Thing?
Answer: It's a testing chip. It goes through the metal detectors to ensure they're working. There's a problem here though. You send X number of testers you get X number back. If you get X-1 or some other number you stop the line until you find your chip. The entire purpose of the test is to make sure that stuff like this--which is supposed to simulate a foreign object--does not get through. There's usually paperwork to document this. Write to the outfit and tell them what you found and rest assured there will be a s**tstorm on the other end.
It's worth mentioning that every now and then a case goes unsolved no matter how popular it becomes. For example, when an active redditor submitted a thing that strongly resembled a specific model of an anti-personnel landmine. "The active account went completely silent for months, causing many to fear that there was a fatal accident, to the point of people scouring news sites for any stories about ordnance fatalities," the moderator recalled. Luckily, the person turned out to be fine; another user tracked them down and contacted them on another website. "Unfortunately, what that sleuthy user did to track down the submitter counts as doxxing, which is against reddit sitewide rules, so his elaborate write up of tracking the person down had to be removed." But that just goes to show how much this community is dedicated to the common cause.

What Are These Characters Found On The Back Side Of A Sign On A Woodland Trail In Alaska?
Answer: It's Stafir Móti Aðsókn an Icelandic magical sigil/stave to protect against ghosts and evil spirits
Sometimes, redditors themselves get in the way of all the detective work. "The most common breach of guidelines is people making jokes, which makes it harder for people to see the correct answer," the moderator explained. "Jokes will get people a temporary ban; more jokes get a permanent ban. It's a pretty simple rule, but a great deal of time is spent weeding those out."
#3
Help Identify What These Are And What They Were Used For? Passed Down By Family - UK
Answer: An apprentice final piece before becoming a journey man engraver.
The moderator said they think the popularity of the subreddit boils down to human nature -- we're curious creatures. "My guess as to why this subreddit is so popular is the instant gratification of managing to solve something using your own knowledge, and people's intrinsic need of figuring out what something unknown is. It's also a great place to learn how to find information quickly, as most of the time there seems to be a race between people to solve the items that have been posted," they added.

Blue Glass Token Found In A Field In France, Though One Of The Ships Flags Kind Of Looks Like A Union Jack. Game Piece Or History?
Answer: It's a part of a ring warn by somone important on one of the shipping companies in the 18th century
Experts think that the roots of our ever-hungry curiosity can be linked to what is called neoteny. This term from evolutionary theory means the "retention of juvenile characteristics". It means that as a species, humans are more child-like than other mammals. Being relatively hairless is one example. A big brain relative to body size is another. Our lifelong curiosity and playfulness, they think, is just another behavioral characteristic of neoteny.

I Know It’s A Chair, But What’s With The Extended Arms?
Answer: It looks like a plantation/planters chair. You’d put your sore swollen legs up on the arms after sitting on a horse all day, like a pregnant woman with her legs up in the same fashion. This is why the back is so sloped as well. If you sit up straight it wouldn’t be comfortable to put your legs up like that, but in a reclined position it’s good for blood flow and air flow.

I Bought This "Thing" Years Ago, But Never Knew What It Was, I Just Thought It Looked Cool! The Center Globe Piece Spins And Is Weighted At One End, So Even If You Give It A Spin, It Always Ends Up With The "10" Facing Up. The Numbers Are 10-130, In Increments Of 10. What Is This Thing?
Answer: This is a thermometer. My grandfather had the same exact device. Look at the number where it aligns with the convex (upper) portion of the plane, that should be the approximate temperature in Fahrenheit. I was always told to not spin it because it would mess with its accuracy

Marcellus the Third 4 years ago
This should be higher up, as most of the others are relatively easy --- e.g. the horrid polyphore mushroom, most people won't find the species or even genus but it is obviously a mushroom; the sugarcube-gripper is very obviously gripping something about an inch diameter; the monopoly pieces are very recognizably the Monopoly man; etc etc. This is so specific that it really is almost impossible to solve!

My Grandad Dug This Up? Found In Liverpool, Possibly WW2, It Was Found With The Decoration On, What Is It?
Answer: Yea ! It’s a thing ! Called trench art , google it there will be tons of beautiful engravings on shells
François Carré 4 years ago
Many soldiers had professional skills in handcraft. Creating art out of battlefield rubbish, like bombshells, was important for these men's mental health. Not only they could practice their skills and pass the time (life in the trenches between deadly assaults was actually dull, uncomfortable and boring) but beyond that, in the middle of this awful wartime, it made them remind they were civilized people, able to create beauty and celebrate life even out of lethal material.

What Is This Appliance Built Into This Kitchen Island?
Answer: I had one of these in my kitchen and I loved it! It was near my regular sink so I could pull the faucet head over to fill the “pot” then I would turn it on to boil the water. It has a pot that goes inside it that has holes in it - like a strainer. You put the strainer inside the “sink” and then toss your items that you want to boil inside the strainer and cover it. Once your food is cooked you lift out the strainer, flip the switch and all the boiling water drains out. The biggest advantage was not having to carry a large pot of boiling water over from your regular stove top to the sink to drain out the water. I used it for boiling pasta, potatoes, corn on the cob and I loved it!! I started to have trouble with it not holding water and when I contacted Kohler the said so sorry, but the model was discontinued. It was great while it lasted!!

#23
What Is This Slack In Power Lines? What Purpose Does It Serve?
Answer: Former CATV tech here. It's called an expansion loop. Coaxial cable (for cable tv) is mostly aluminum which expands and contracts with temperature changes moreso than the steel supporting strand to which it is attached.
If this expansion loop wasn't there, the cable would literally suck out of the compression fittings in the Winter and kink in the Summer.
Leo Domitrix 4 years ago
Slack in power lines ----- not this example, but in general ---- is to allow for seasonal compression/expansion, and also, if you don't have enough slack ---- one bad wind and there goes the whole power line... Always leave slack.

What Is This Scanner That A Rooftop Cop Had At A Protest? Seemed To Be Shining A Green Laser At Certain People In The Crowd
Answer: Picking out specific targets for ground police. It’s easier to track an individual through a crowd from above. This may be because they are armed, or something else that makes them high priority. Snipers are out of the question, firing into a fast moving mass of people would only end badly.
Ray Heap 4 years ago
A green laser shines at 530nm, this frequency will do the most damage to a human eye as your eyes are most sensitive to a wavelength of 530nm. Incidentally this is the wavelength that will penetrate the deepest underwater. A little evolutionary left over from our aquatic days perhaps?

These Lead Blocks Were Found In A UK River. 125g Each. Can Anyone Positively Identify Them?
Answer: These are jyotish tokens with the Rahu yantra to be used for a Rahu Ranga Mantra recital and practice. Likely for personal gain.
You are right that these are magic squares, but more specifically they are called Navagraha Yantras. There are traditionally 9 of them (one for each "planet"), each having a distinct combination of 9 numbers. Together they can be combined to form their own "Magic square".
The words on the bottom are some form of either:
- om raam rahave namah
- om raag rahave namah
- or simply, om rahave namah
The placement of Lead (raanga) in running water is particularly important in this practice as a remedy for specific things and astrological circumstances.
Curious about the cube form though. May have something to do with counting and keeping track of the number of times the mantra has been recited (supposed to be 18,000 over 40 days)

i need to find this subreddit and post a pick of something i am trying to figure out. i have two 'things' that have the family initial engraved on it. kind of looks like a mushroom with a large cap (where the initial is) and the 'stem' has a smaller 'cap'. i think it was kind of a buttone from the 1700s or so. but, if you flip them over and look inside you can see they were made from coins. still, have no idea what they are.
