Here are the key facts extracted from the text:
1. The colors of the rainbow are arranged in the order of the acronym "pheasant sits" (Purple, Hue, Every, Angle, Sunset, Takes, In, Sight).
2. The phrase "we give juicy lemons" can be used to remember Latin numerals (W=50, G=100, J=1000, L=50).
3. A study was conducted with 360 subjects to determine how people choose their moves in rock-paper-scissors.
4. Most people choose their moves based on psychological patterns.
5. Men tend to start with "rock" in rock-paper-scissors, while women tend to start with "scissors".
6. If an opponent repeats the same gesture twice in a row, they are unlikely to repeat it a third time.
7. A person tends to imitate their own kind, so showing an opponent the "scissors" gesture before a game can influence their choice.
8. By counting the number of fingers from the sun to the horizon, you can estimate the time before sunset (each finger is approximately 15 minutes).
9. There are several winning combinations in tic-tac-toe that can be remembered and used to guarantee a win.
10. A person's hand can be used as a ruler, with the distance between the thumb and little finger being approximately 20 centimeters.
11. A trick can be used to guess a number between 1 and 10 by multiplying the number by 9, adding the individual digits, and adding 4.
12. A trick can be used to guess a three-digit number by writing the number twice, dividing by 13, 7, and 11, and getting the original number as a result.
13. The fingers on a person's hand can be used to estimate angles in degrees (little finger and ring finger = 30 degrees, little finger and middle finger = 45 degrees, etc.).
14. The moon's phase can be determined by drawing an imaginary line next to the moon (if it forms the letter "p", the moon is waxing, if it forms the letter "c", the moon is waning).
15. In billiards, taking your time before hitting the ball, aiming carefully, and exhaling before hitting can improve your chances of winning.
