20 Things That You'd Need Seriously Sharp Eyes To Discover

She has a tendency to hide money in her gifts and if you look closely, you can see a little cash peeking out of the right side of the brush next to the word "Colgate."

As the uploader explained, they're a part of the cleaning crew that regularly works a Jimmy Johns locations and staff there apparently leave these behind to ensure the cleaners "did their job."

Not only is this the perfect way to make a cleaning crew hate you, but one commenter pointed out that it's not even an effective way of testing them because cleaners are often instructed not to touch anything that doesn't belong in the trash.

So these might remain untouched even if the place is spotless. Maybe somebody should spend less time honing their hiding skills and more time honing their people skills.

And while this house's new owners discovered that the room is mostly full of disorganized junk, it does apparently contain a book about the flora and fauna of Central America that was printed all the way back in 1706.

That's quite the amazing (and potentially lucrative) find.

From there, they were amazed to learn that this "hello from Seattle" message has been appearing on Xbox consoles since the original model came out in 2001.

I was always more of a Playstation kid so I can't really say I knew that either.

After all, this switch doesn't open a panic room or a treasure hall or something.

All it does is turn on the light in the little hallway between the bathrooms and the main part of an Italian grocery store.

Apparently, this wasn't sold as a standalone magnifying glass, but rather as part of a kit that also included a screwdriver.

So instead of being a general magnifying glass, it was specifically intended to make it easier to work with particularly small screws. That explains that.

After all, these are just floor tiles that could be anywhere, right? Well, look closer and you may see a familiar fold in the large gray tiles. If not, that little "stamp" at the corner of each of the smaller tiles should serve as a bigger hint.

That's right, this is what the floors look like in the U.S. Postal Museum.

And while most of us likely wouldn't notice this in the wild, you've probably spotted that one of their suggested scenarios for this jug is a zombie apocalypse.

Personally, I think one apocalyptic year is more than enough, thanks.

While vegetation overtakes the structures we put in certain areas all the time, the pattern of growth here seems a lot more deliberate.

Namely, that the Rubik's cube they painted is unsolvable and that's not just because it's a solid concrete block.

It's because there are two yellow squares that share an edge. That evil genius.

It's hard not to be impressed by the fact that they were able to hide such a large container in a hollowed-out stump.

At the same time, I can also see how it would be maddening to try and find this.

And while we've been trained to be suspicious of bookcases and paintings by movies, it turns out that the real treasures were disguised by the boring old filing cabinet all along.

Those 20 cent coins weren't just there for fun, they were there to help level the door out. So when the uploader reinstalled the door, they followed the plumber's lead and put them back.

And while the name of this New Zealand crane may sound cute on its own, it's actually a clever reference to a nationally famous rugby player named Richie McCaw.

And I can't help but feel oddly satisfied that the first place their minds went when they were talking about jazz apples was Bee Movie.

Unless they're just genuinely curious as to whether I like jazz and have no idea what I'm talking about.

It's subtle but you might notice some dots and dashes under the L in this logo. That's apparently Morse Code for the letters J and L.

Once this one was damaged enough to chip away the outer shell, it was discovered that it had a different pool ball inside of it all along.

I guess the "3" ball here got a promotion.

Apparently, you have three options when you encounter a feature like this on a building sight. You can either get a bunch of explosives and blow it up, spend a whole of of money and time getting the equipment together to break it up and haul it out in pieces, or simply build around it.

As we can see, they went with the easiest option in this case and I suppose it worked pretty well since the boulder was only revealed long after the fact.

As we can see, someone who was caught in a dangerous situation during World War II hollowed this book so they could hide a pistol and its magazine inside.

Since this is now on display in the Gestapo Museum in Kraków, Poland, I think we've got a sense of how desperate their circumstances were.

Anyone who's had to deal with an engine block full of acorns knows that but it's also evident in the way this spider concealed itself in a socket.
