If you’ve never noticed the tiny hole at the bottom of airplane windows, you certainly will from now on. The pin-sized opening is barely visible, but it serves several significant purposes. A minor perk of the small hole is that it prevents the window from fogging up. It allows you to get those magical views as you’re landing and taking off without having to wipe it down first.
The most important purpose the hole serves is to allow airflow into the plane. This prevents air pressure from building up to dangerous levels that are capable of cracking or shattering the window. It’s a small feature, but it’s ultimately ensuring passengers don’t get sucked out of the plane and dropped from the sky.
Notebook Margins
Remember back in grade school when using paper with properly sized margins was a huge deal? Well, as it turns out, margins weren’t created to give students extra room for their notes. The reason they were first used is actually quite disturbing. Back during a time when rats were a common guest in most homes, they would often snack on pieces of paper.
The margins were put in place to keep all written content away from the edges of the paper, safeguarding it from any rats with the munchies. Additionally, it would help to ensure any wear and tear that naturally occurs over time to the paper edges wouldn’t damage what was written down. Basically, whatever they were writing back when margins were created must have been incredibly important.
Vehicle Headrests
Vehicle headrests are, first and foremost, designed for our comfort. They are adjustable to support people of most heights, but not everyone knows they also offer a built-in safety feature. In the unlikely event that you become trapped in your car and can’t get the windows to open, the headrest can be pulled out of the seat entirely.
It’s held in by two sturdy metal prongs that come to a dull point. For this reason, they can be used to quickly break a car’s windows, allowing you to escape safely. This is one not-so-small fact that more people should be made aware of!
Indentation In Wine Bottles
Wine aficionados are certainly familiar with the indentation found on the bottom of wine bottles. Coming in a variety of shapes and sizes, it doesn’t actually indicate whether a bottle of wine is superior, as many have been led to believe. The indentation called the punt, dates back to when bottles were being handblown.
Glassblowers would push in the base of the bottle to stop a nub from forming that would prevent the bottle from standing upwards. Today, some brands continue the tradition by including a punt, even though it doesn’t serve a purpose. On the contrary, carbonated drinks like champagne require a punt, as it evenly distributes the pressure from the carbon dioxide.
Wooden Coat Hangers
Wooden coat hangers have a reputation for being fancier than plastic and wire alternatives, but there’s a reason they come with a larger price tag. Often made of cedar, wooden hangers actually serve a unique purpose that makes them well worth the extra cash.
Not only does cedar produce a scent that few can say they don’t love, but it also keeps away any bugs or moths that might chew at your clothes. They’re also far more durable than other options, making them ideal for storing heavy winter coats during the warmer months. Yes, you might spend more money on these hangers upfront, but they’re ultimately saving you cash in the long run by helping to preserve your wardrobe.
