It is embarrassing, but we should admit it: sometimes when you borrow your friend’s car or you are driving a rental car, you pull up at the gas station to get juice for the car, just to be told that you have placed the car at the wrong side.
This is where the arrow next to your gas gauge comes handy since it points out to the side of the car’s gas cap is on and saves you from the embarrassment. But as a cautionary act, try to check the side of the gas cap before riding the car, because maybe it won’t contain any pointing arrows.
A Bobby Pin

Ladies! Have you ever thought that maybe you are using your bobby pin wrong? Have you ever wondered why one side of the pin is straight while the other is bent into zigzags?
You should know that the grooved side indicates that it is the bottom of the pin, and it is the one that should be facing the hair. The zigzags help in making the bobby pin more effective and hold the hair tighter.
The Second Hole On The Padlock

We usually don’t pay attention that there is a second hole at the bottom of the padlock, and we only care about the keyhole. However, that small hole is really important for various reasons: to begin with, it helps in clearing the lock from water in case you are using it outside.
This way, the inside of the lock will not rust or freeze. Also, in case your lock became stiff, you can use that hole to oil it and keep it functioning.
The Thick Bit On Cables

You may notice that there are cylinder-shaped lumps on some cables; especially computer ones.
These bits are called ferrite cores or chokes, and they are composed of magnetic iron oxide that serves to abolish high-frequency electromagnetic interference.
In other words, for people who use speakers, you will probably see that getting your mobile phone near the speaker will generate weird interferences. This is the reason why these lumps are important in keeping that from happening to your devices.
Utility Blades

If you take a closer look at the blade on the box cutter or utility knife, you will realize that there are some score lines along with the cutter.
These score lines are there for a valuable purpose. When your blade becomes blunt, you can cut them off and use the following one without having to buy a new knife.
Take off the cap at the back of the knife, slide the blade out at the back end, and cut it using the cap. And then, reassemble the knife and it will be sharp.

We all have been amazed when seeing people’s ability to write on the computer without looking at the keyboard even once. These people usually use their 10 fingers effectively and write at a great speed.
In addition to their memory of each key on the keyboard, these people are using the F and J keys as references before they start typing. These two keys contain small bumps that serve as indices for the starting point. Now you know the secret, and with little practice, you can be just like them.

If you have ever been wondering why the wings on the Apple power cable (facing each other) are there? We have the answer for you. These plastic curves are functional if you want to wrap the cable around them.
First, wrap the dense part of the cable around the block, then use the wings for the thinner section. Thereafter, secure the cable with the small clamp on the end. This is a really convenient way to take your power cable with you in small bags.
The Disc On The Bottle Lid

You most likely noticed that the bottle closes well even without the little disc under the lid. However, this small disc plays an important role: it is there as a line of defense against leakage from the bottle.
It helps to seal the bottle and keep everything inside such as liquid and carbonation. So without this small part, your favorite soda will taste awful and you’ll probably have to buy a new one.
Bonus:
• The holes on the ruler serve to hang it up.
• The spikes on some caps help you to penetrate the protective foil.
• The dot on the back of the iPhone helps you to capture the sound when you are using the back camera.
• The Tic Tacs package has a special design to get you one at a time.
