Why Is This Here? The Surprising Stories Behind Everyday Oddities
Have you ever stopped mid-step in a parking lot, stairwell, or hotel hallway and thought: Why is that there? A random metal pole in front of a store. A tiny pocket on your jeans. A blue strip on the edge of a razor. A bricked-up doorway in an old building. These everyday oddities often fade into the background of modern life — yet almost all of them have fascinating origins.
Many of the features we ignore today were once ingenious solutions to very specific problems. Some are relics of outdated technologies. Others are remnants of older laws, safety measures, or social customs. A few exist simply because changing them would cost too much money.
This deep dive explores the surprising histories behind everyday design quirks — and shows how the past quietly shapes the world around us.
1. The Tiny Pocket in Jeans
If you wear jeans, you’ve probably noticed the small fifth pocket tucked inside the right front pocket. It’s too small for a phone and barely fits coins. So what is it for?
The answer traces back to the 19th century and the early designs of Levi Strauss & Co.. When durable denim work pants became popular among miners and railroad workers in the American West, pocket watches were common accessories. To protect these watches, manufacturers added a small reinforced pocket specifically designed to hold them.
It was called a “watch pocket.”
Even though pocket watches are rare today, the design stuck. Removing it would change the classic silhouette of jeans — and consumers expect that familiar structure. What once protected a miner’s timepiece now survives as a fashion relic.
2. The Blue Strip on Disposable Razors
Modern disposable razors often feature a blue or green lubricating strip at the top of the blade. It fades with use. Is it decoration? A marketing trick?
The strip was introduced to reduce irritation and improve glide. Companies like Gillette developed lubricating polymers infused with aloe or vitamin E. The color fade signals that the lubrication is wearing off.
Interestingly, the visual fading mechanism is also psychological. Consumers are more likely to replace blades when they see visible wear — even if the blade remains usable.
So the strip serves both a functional and behavioral purpose.
3. Bricked-Up Windows and Doors
In older cities like London, you may notice windows that appear to have been filled in with brick. Why would someone build a window just to block it?
The explanation lies in the 1696 Window Tax introduced in England. The government taxed homes based on the number of windows, believing wealthier households had more of them. To reduce tax burdens, property owners bricked up windows.
The tax remained until 1851 — long enough to leave architectural scars across Britain.
What looks like strange design is actually a 300-year-old tax workaround.
4. The Extra Hole in Converse Sneakers
If you’ve worn classic canvas sneakers like Converse, you’ve probably noticed two small metal eyelets on the inner side of each shoe.
They’re not decorative.
Originally designed as basketball shoes, these eyelets served two purposes:
Ventilation
Alternate lacing techniques for better ankle support
Today, most wearers use them casually — but their athletic origins remain stitched into the design.
5. Why Keyboard Layouts Are So Odd
The QWERTY keyboard layout seems arbitrary. Why not alphabetical?
The layout dates back to the 1870s and was developed for early typewriters by Christopher Latham Sholes. Early mechanical typewriters jammed when commonly paired letters were typed quickly.
The QWERTY layout was designed to separate frequently used letter combinations to prevent mechanical clashes.
Ironically, what began as a workaround for machine limitations became the global standard — long after the original problem disappeared.
6. Those Metal Bollards in Front of Stores
Have you noticed sturdy metal posts outside convenience stores and supermarkets?
They’re called bollards.
While they can guide foot traffic, their primary purpose is safety. After multiple accidental vehicle crashes into storefronts, building codes increasingly required protective barriers.
The rise of automatic transmission vehicles and distracted driving contributed to these incidents.
What appears to be urban clutter is actually modern crash protection.
7. The Hole in Airplane Windows
Commercial airplane windows often have a tiny hole near the bottom. Why would an aircraft designed for high-altitude pressure include a hole?
Aircraft windows are made of multiple layers. The outer pane handles pressure differences. The tiny hole, called a bleed hole, regulates air pressure between panes and prevents fogging.
The design is part of a layered safety system used by manufacturers like Boeing.
A small hole prevents catastrophic pressure imbalance.
8. Why Manhole Covers Are Round
Manhole covers are almost always round.
The reason is practical: a round cover cannot fall through its own opening. Any other shape could potentially drop in if angled incorrectly.
Additionally, round covers are easier to roll when transporting.
A simple geometric truth shaped urban infrastructure.
9. Why Gas Pumps Have Those Clips
Fuel pump handles have small metal clips that allow hands-free fueling.
They exist for convenience — but also regulation. In some U.S. states like New Jersey, self-service fueling was historically restricted, meaning attendants controlled pumps.
Different states adopted different safety standards, which explains why some clips function differently depending on location.
Regulation shapes design more than we realize.
10. The Arrow Next to Your Fuel Gauge
Many modern vehicles display a small arrow near the fuel pump icon on the dashboard.
That arrow tells you which side of the vehicle your gas cap is on.
This simple feature was introduced as manufacturers noticed drivers frequently forgetting which side their tank was on — especially with rental cars.
It’s a small detail, but one born from repeated everyday confusion.
11. Why Escalator Brushes Exist
If you’ve looked closely at escalators in malls or subway stations, you may notice small black brushes along the sides.
They are not for cleaning shoes.
The brushes create a psychological boundary, encouraging riders to stand slightly inward and reducing the risk of clothing or shoelaces getting caught in the mechanism.
It’s behavioral engineering disguised as maintenance.
12. The Dip in Wine Bottles
Most wine bottles have a deep indentation in the bottom called a punt.
Historically, punts strengthened hand-blown glass bottles, which were prone to uneven thickness. The indentation improved structural stability.
Today, modern glass doesn’t require it — but the tradition remains. It also aids in pouring and sediment collection.
The punt survives as both function and legacy.
13. The Ridge on Coins
Many coins have ridged edges.
In centuries past, precious metal coins were shaved at the edges by criminals seeking small amounts of silver or gold — a practice called clipping.
Reeded edges made tampering visible.
Even though most coins today aren’t made of precious metal, the ridges remain.
Anti-fraud design became aesthetic tradition.
14. Why There’s a 57 on Heinz Bottles
The “57 varieties” slogan of Heinz was never accurate — even when introduced.
Founder H.J. Heinz liked the sound of the number 57. It was marketing psychology, not math.
Even more interesting: the raised “57” on glass ketchup bottles marks the sweet spot to tap when pouring thick ketchup.
Branding meets practical instruction.
15. The Folded Corner on Mattress Tags
You’ve likely seen a mattress tag that says “Do Not Remove Under Penalty of Law.”
The warning applies to retailers — not consumers.
In the early 20th century, mattresses were sometimes stuffed with unsanitary materials. Laws required labeling to protect buyers.
The intimidating language remains decades later, confusing countless customers.
16. Why Stop Signs Are Red and Octagonal
The modern stop sign’s shape and color were standardized in the 20th century to improve visibility and recognition.
The octagon allows drivers to identify a stop sign even from behind.
Standardization across the U.S. was overseen by agencies such as the Federal Highway Administration.
Design was shaped by reaction time studies and accident data.
17. The Black Stripe on Rear Car Windows
Many cars have thin black dots or stripes along the edge of rear windows.
These are called frits.
They help distribute temperature evenly during manufacturing and protect adhesive from UV damage. The gradient pattern reduces optical distortion.
Aesthetic detail meets structural necessity.
18. The Reason Hotel Blankets Are White
Hotels shifted to white linens in the 1990s to signal cleanliness.
Chains like Westin Hotels & Resorts popularized the “Heavenly Bed” concept, emphasizing crisp white bedding as a luxury signal.
White linens also simplify laundering and bleaching.
Perception drives hospitality design.
19. Why USB Plugs Are Frustrating
The original USB design was not reversible due to cost and manufacturing simplicity at the time of development.
Later versions like USB-C corrected this flaw — but billions of legacy devices keep the old format alive.
Compatibility often outweighs perfection.
20. The Mystery of Sidewalk Lines
Sidewalk sections are divided by lines called expansion joints.
Concrete expands and contracts with temperature changes. Without these joints, sidewalks would crack unpredictably.
What appears decorative is actually preventative engineering.
The Bigger Pattern
What connects these oddities?
Three forces:
Historical Legacy – Old solutions that remain (watch pockets, QWERTY).
Safety & Regulation – Design shaped by law (window tax, mattress tags, stop signs).
Human Psychology – Design influenced by behavior (escalator brushes, white bedding, fading razor strips).
Our environments are layered archives of past decisions.
Final Reflection
The world is full of silent design stories.
That extra pocket.
That bricked window.
That tiny airplane hole.
Each began as a response to a problem — technological, social, economic, or regulatory. Even when the original problem disappears, the solution often remains, preserved by habit, cost, tradition, or familiarity.
Next time you spot something that makes you ask, “Why is this here?” — remember:
It probably has a story.
And those stories reveal how history quietly shapes the ordinary.
