Changing the car’s tires in time is a life-saving thing. Driving with worn-out tires on a wet road, for example, can make you lose control over the car and be in a very unpleasant situation.
The small rubber bumps on the tires indicate exactly when it is their time to be changed. If they are worn out, it is time.
Believe it or not, there is a reason for the darker shade on the eraser, and no, it's not for erasing different ink marks (as we used to think).
Apparently, the white part of the eraser is used for erasing marks off regular pieces of paper, and the darker (or different colored) shade is for erasing pencil and other marking from more sensitive papers. Who knew?
The Lines on a Solo Cup
The solo cups came to life in the 1970s, being the first disposal cups to be used. Solo seemed to be a great name for something that was intended to be used only once. Have a look at this interesting detail on the cup that most users haven't noticed.
The lined decorations of the cup are there to measure up the liquid. The bottom line, for example, is a recommended serving for any type of liqueur, the middle for wine, and so on. So when you're at your next party and wine is served in solo cups, make sure no one tries to rip you off.
Every item bought these days has one of these hiding somewhere. Did you ever ask yourself how do tiny bags full of silica gel beads manage to observe so much moisture and keep our things fresh and dry?
These magical silica beads can observe up to 50% of moisture, so next time it gets too humid and too sticky, use a silica gel pack and let it do its wonders.
We all know that everyone can adjust the headrest to their own height. But did you know what lies behind the two metal bars that are left sticking out of the seat? Survival everyone, survival.
If you are accidentally caught inside a car with no way out, remember this. Detach the headset and use the metal bars to smash one of the windows. Apparently, there are things that can be found in your car's headrest you never knew of.
