The video discusses ten items that we use daily but often don't fully understand their purpose.
1. The iPhone camera's flash hole: This tiny hole, often seen as an ornament, actually functions as a microphone. It reduces background noise, allowing for clearer communication and better-quality audio recording.
2. The book flap: This seemingly useless strip is designed to separate pages, saving money on special separators.
3. The third peak of the plug: This element is crucial for safety. It directs energy to a second place, preventing overloads or short circuits that could damage equipment.
4. The texture of toilet paper: The figures on toilet paper are not decorative but functional. They help grab excrement, making cleaning easier.
5. The holes in tennis shoes: These holes at the edge of the shoes are not for style but to provide greater support for the foot, reducing the chances of blisters.
6. Gel bags: These are silica gel bags that absorb moisture, preventing new clothes or shoes from having a bad smell.
7. The E and F keys on a keyboard: These keys have small edges that serve as starting points for our fingers, helping us write more quickly.
8. The hole in a popsicle stick: This hole allows the candy to be doubly attached, preventing it from coming off the stick.
9. The transparent plastic inside the lids of certain bottles: This plastic prevents gas from escaping, sealing the lid and preserving the properties and content of the drink.
10. The tiny holes on the side of headphones: These holes increase the quality of sound and release sound vibrations, extending the life of the headphones.
