I Found This Ring In My Backyard While Doing Gardening. After Cleaning It, It Doesn't Look Like A Normal Ring. Any Ideas ?

Answer: It's a Georgian/early Victorian mourning ring. The initials belong to the lost loved one.
They were typically made from gold (18k+) and enameled in black. Yours looks like it was made around 1820s-40s.

The ‘What is This Thing’ subreddit is very large: more than 1,170,300 people (and counting) are part of this community. Which just goes to show just how many people are drawn in by a desire to figure out modern mysteries about vintage things. Or how many Sherlock Holmes and Castle enthusiasts actually prowl the streets at night, looking for cases to solve. You never know, your own neighbor could be one of these everyday heroes, helping others figure out answers to questions that won’t let them sleep at night.

This Weird Wrapped Car. The Lights Were Wrapped In Cloth. Serial Numbers All Around. Anything Significant Or Just Tacky?

This Weird Wrapped Car. The Lights Were Wrapped In Cloth. Serial Numbers All Around. Anything Significant Or Just Tacky?

Answer: It obscures the car while being test driven, so the yet-to-be-released models are not photographed and published. The random "wave" patterns effectively hide the body contours and lines.

Some of you might be thinking that my talks about mom-and-pop internet detectives are a bit far-fetched. But, the interesting fact is, that there are plenty of amateurs who have solved major mysteries! For example, BBC Future writes how Carl Koppelman got fired from his job at Disney and became a detective in his spare time.

Koppelman is now the moderator of “The Unidentified” subforum on the Websleuths website and holds himself personally responsible for solving three mysteries. He matched three unidentified people in coroners’ reports with their missing person profiles. Among them is Lynda Jane Hart, whose remains were found in 1988, but identified only in 2011. If Koppelman can do this in his spare time, imagine what other mysteries we could solve if we joined forces!

In A Multi Storey Car Park. Is It A Passage For Rats? There Are Also Small Holes In The Floor And Ceiling With A Tiny Ladder Connecting Them

In A Multi Storey Car Park. Is It A Passage For Rats? There Are Also Small Holes In The Floor And Ceiling With A Tiny Ladder Connecting Them

Answer: Secret Industry by John Pym: The stairwells and lift lobbies of multistorey car parks are not usually areas where people pause to admire the architecture, so John Pym used this to his advantage. The model walkways and ladders replicate their full-scale counterparts and are a playful way of suggesting an alternative, unseen service industry at work within the building. Superficially mundane, some people may use the car park for years without being aware of their presence, while others will notice straightaway. The artist sees it as a reward for those who look more closely at their surroundings.

What Is This Fish With Strange Writing?

What Is This Fish With Strange Writing?

Answer: The Lucky Iron Fish. I recall hearing that iron deficiency was a serious problem in developing countries due to improper diets that consisted of mostly pastas and rice, which are a poor source of iron.
The solution was to boil chunks of iron with food to increase the iron content but many were skeptical and hesitant to cook with chunks of metal in their food. The iron was shaped into a 'lucky fish' that would provided addition health benefits when you boiled water with the fish in it.

What Is This Weird Half Truck And Why Is It Pushing A Flatbed Trailer? Is There Any Sort Of Advantage Of Pushing Rather Than Pulling It?

What Is This Weird Half Truck And Why Is It Pushing A Flatbed Trailer? Is There Any Sort Of Advantage Of Pushing Rather Than Pulling It?

Answer: Float Plane Mover. This truck's job is to move planes up and down a boat ramp into the water. Backing up an ordinary truck+trailer combo down a boat ramp is not easy. With this vehicle, the driver can look straight forward down the ramp rather than in his rear-view mirror, and since the steering wheels are at the back it's easy to align the truck's bed with the plane. Most trucks only load at a boat ramp once in a while, since this one does only that, it makes sense to design it specifically for that job.

20 Years Of Research And Reddit Is My Last Hope! What Is This Thing?

Answer: The Black Drum fish fossils. The Black Drum had a short deep body with a high arched back, but a flattish belly. The jaw teeth were small and pointed, but the throat was armed with large, flat, pavement-like teeth with which the drum crushed shellfish, for food. This characteristic separates it from the weakfish and the king fish.
