We come across Everyday things that we do not know the real purpose of. Let’s get to know such 10 hidden secrets here!!!
1. Extra piece of fabric and button with garments
Often clothes come with an extra piece of fabric and button. These can be handy if there’s a small hole or a button falls off, but this isn’t its primary purpose. The real purpose of the fabric piece and the button is to test out detergents or stain reaction to the fabric and button, so unintentionally you don’t ruin your new material.
2. Book ‘Dust jacket’
Also called the Book Jacket, Dustwrapper, or Dust cover. It usually has the book title and name of the author & useful for guarding the book from unworthy distortions. You can also use a dust jacket as a bookmarker, thus offers redemption to anyone tempted to bend the page corner.
3. Gas/Petrol Gauge Arrow
In many of the new vehicles, you would notice an arrow on the left or right side of the fuel or gas gauge. This arrow points to the side of your fuel tank. So next time you do not have to get out of your car, to validate the fuel cap side.
4. Dimples On Golf Ball
Have you ever wondered why golf balls have so many dents? Well, the dimpled ridges in a golf ball create a turbulent boundary layer of air that clings to the ball’s surface. Thus, reducing the amount of air drag and allowing the ball to go a little faster and farther.
5. Hole in Padlock
How come padlock is so durable in an extreme environment? Believe it or not, it’s because of this tiny hole at the bottom of the Padlock. On rainy days the water seeps out, or if a padlock is stuck then lubrication is applied through this hole. Similarly, Padlocks without a hole are considered indoor locks. Also, a strong wire tip can easily bend using this hole which then can be used to open locks in case you lost the keys. Scary, isn’t it!
6. Keyboard Keys Irregular Layout
In the olden days, the keyboard layout called the ‘Dvorak’ design had vowels and some consonant letters on one side and remaining consonant on the other side. The modern or present keyboard layout is called the ‘QWERTY’ or ‘Universal’ layout, which was design in the 1860s for the purpose to slow typists down because typists with Dvorak layout would type so fast that usually, the typewriter strings would get jammed. The modern keyboard also has bumps on ‘F’ and ‘J’ keys for users to correctly position their hands on the keyboard without looking at the keyboard.
7. Toilets with huge gaps
There are many obvious reasons for the toilet doors that have gaps at the bottom such as better air circulation, easier to clean, easy to see if it’s occupied, and in the case when someone is out of toilet paper, they can easily be helped out from the nearby neighbors. The public toilets are also not fully enclosed so that people do not spend a lot of time on that comfortable seat playing with their gadgets!
8. Watch pockets
In the early days when there were no cell phones, people used to carry small watches, especially men usually carried their watch in their jeans or waistcoat small pocket called fob pocket. Presently, these small pockets are now designed for fashion purposes just like the extra button jeans which were first used for protecting the weak points of the jeans.
9. Utility knives
The plastic end cap of the utility knife has its unique purpose which I bet you wouldn’t have heard before. Have you ever noticed that the utility blades have scales, meaning the knife can be used more than once with sharp edges? The easy way to separate these blades is through the plastic end cap of the utility knife, and then by using the slider bring the sharp blade to the front for further use.
10. Tab/switch of the rearview mirror
The rearview mirror is designed to reflect around only 4 to 5 % of the incoming light. In darker surrounding when you are stuck with the higher beam light of cars behind you, simply tab/flip the rearview mirror which will adjust to an angle that the incoming light will no longer bother you.
