As children, we may feel that much of the knowledge we acquired at school will be difficult to apply later in life.
In fact, this is not true: many school life hacks are now more relevant than ever.
Determining the phase of the moon
It is very easy to determine whether the moon in front of you is waxing or waning.
Connect the corners of the moon with a vertical stick: if you get the letter P, the moon is waxing, and if you get the letter C, the moon is waning.
Calculate the time until sunset
One finger is approximately equal to 15 minutes. Now let's position our fingers so that the sun "touches" the index finger.
If there are 4 fingers left until sunset, there is still an hour until sunset.
Find out the number of days in a month without a calendar
We clench our hands into fists and start counting: the first knuckle is January, the hollow is February, etc.
Each domino shows a month with 31 days, and each cavity shows a shorter month.
Checking the battery charge
Hold the battery vertically and drop it from a small height. If it falls on its side, it is discharged; if it bounces but remains vertical, it will still work.
Remembering the colors of the rainbow
Remember the phrase "Every hunter wants to know where the pheasant sits"? If you have already forgotten, then it's time to refresh your memory, since each word in it begins with the same letter as a color of the rainbow.
Earlier we wrote about how to memorize traffic rules in no time.
