20 Weird Things People Seriously Struggled To Identify On Their Own

However, that didn't stop someone from providing a specific solution to this mystery. It turns out that this is a whale oil lamp of Dutch origins that's designed to hang on a wall.

However, the fact that adjusting it seemed to change a percentage made them realize that couldn't be its purpose and left them wondering what it actually does.

The answer, it turns out, is that it's used to regulate the humidity in a room rather than the temperature.

But while it didn't show any identifying marks, that apparently didn't stop people from figuring out that it's a fob used to open computerized door locks.

As for why it was dangling from a post? Perhaps someone assumed that whoever dropped it would be looking for it.

And indeed, that's true because this was apparently how Nokia's customers used to secure their old Bluetooth headsets to themselves.

They thought it was a bullet but the unfortunate truth is that it was actually fired by a 20 millimeter cannon, which means it could still have some live explosive components.

But while it soon became clear that this thing's discoverer would need to get it checked out, they may never know how it ended up in their wall because their house is 130 years old.

They found it in New York City but whoever brought it there had likely bought it as a souvenir in South America.

Since the figures depicted on it were famously icons of the Incan Empire, it's likely that the tourist who bought it was traveling through the ancient civilization's former territory on the continent's west coast.

Nonetheless, one commenter recalled seeing something like it when they took apart an electric treadmill for its motor. This experience told them that this was one of a treadmill's drive rollers.

As it turns out, this object's placement in a cemetery makes a lot of sense as it's a font for burning offerings to memorialize someone who passed away.

Such devices are fairly common in various communities throughout Asia but the kind of offerings seem to depend on who their burning is intended to honor.

Fortunately, it was much more familiar to others, who informed them that this is a cross stitching hoop used to hold the fabric taught and make more precise work easier.

However, this doesn't appear to be the case and the uploader was finally satisfied with that answer when a commenter explained that this is a decorative cup from Poland called a cyrpok goralsk.

Fortunately, some commenters were able to fill them in and tell them this is known as a hamza with one such person noting that it's considered a symbol of good luck.

As for the bull on it? That represents the second month of the Jewish religious year known as Iyar, which falls between April and May.

And once they knew the answer, they understood why it was there.

This is an old water tank that was placed on its side and left here after the house's previous owners had replaced it with a combination boiler system.

As the uploader put it, "Yeah the previous owners were pretty bad at disposing of rubbish."

And it was a good thing they got curious because it turned out to be the relief port for the house's gas regulator.

With that in mind, it's probably a good idea to clear all that gunk out. This isn't something you want clogged.

Apparently, these details were enough to help somebody zero in on the fact that this is a sheet metal nibbler used to cut the stuff.

But as other users soon explained, this strange little delivery indicated that their information was being used for a "brushing scam" that allows sellers to artificially boost their online review scores.

How it works is that a cheap little item is sent to a real address but that "transaction" allows the fake account that ordered it to leave a glowing review on whatever the people behind the scheme are actually selling.

And that's because they actually have a very specific job. They're used to mount and remove piston rings from various vehicles.

Instead, this is a "palm" that's used in making leather and heavy canvasses like a boat's sails.

Since both of these materials are thick, the central piece is supposed to support the needle that the wearer would try to push through them.

And apparently, something like this has to be smooth and lightweight because otherwise, it would be pretty uncomfortable to wear as a hair pin.

And it's hard to find a device more obscure and oddly specific than this balloon knotter. As the name might suggest, it's supposed to help people tie the ends of balloons.

And judging by the fact that they were activated, it was apparently a pretty cold day when they came across this since that blue light is supposed to show when temperatures go below zero.

That makes this a warning light indicating icy roads.
