01. Vaginal fart
★ A girl can have vaginal farts or vaginal flatulence or vaginal gas or “queefing,” which is just the release of air trapped inside the vagina. It can vary considering a woman’s age, sexual activeness, sweat, feminine hygiene products, tense muscles, etc. Vaginal fart may or may not produce sound. It’s a fairly common phenomenon for anyone with a vagina, at any age. Even our nose farts.
02. Penile fracture
★ A man’s penis can be fractured. It is called a penile fracture. A penis fracture differs from other fractures in our body part because the penis has no bones. It is a severe form of bending injury to the erect penis that occurs when a membrane called the tunica albuginea tears. Penile fracture is very very rare.
03. Cat’s roar
★ Cheetahs can’t roar. They can only meow like domestic cats. There are 38 species of cats on this planet. Most of them are relatively small. Big cats like lions, tigers, leopard, and jaguars can roar because these species belong to the Panthera genus and have a ligament in their voice box that can be stretched to create a larger sound-producing passage resulting wider range of pitch. The lion’s roar is the most famous and can be heard up to five miles away.
04. Ten percent brain myth
★ It is a myth that humans only use 10% of their brains. We’re even using more than 10 percent when we sleep. We use virtually every part of our brain. The brain uses 20% of the body’s energy and contributes to three percent of the total body weight.
05. More than five senses
★ Human beings are not just limited to five sense: Sight, smell, touch, taste, and hear. We have more than five senses.
06. Pink milk
★ Hippopotamus milk is bright pink in color. This is a popular myth about animals belonging to a group of mammals. Hippos produce white or off-white milk (like all mammals). Hippopotamus produces two secretions: one red (hipposudoric acid) and one orange (norhipposudoric acid). Hippos have no actual sweat glands, but they do have mucus glands, which release an oily secretion frequently referred to as blood sweat. There are two distinct pigments in the secretion: one red (hipposudoric acid) and one orange (norhipposudoric acid). When this secretion first appears, it is colorless. Under the sun, it turns reddish-orange in minutes and then later turns brown. However, it is neither blood nor sweat. Blood sweat not only serves as a natural form of sunscreen and moisturizer for the animal’s sensitive skin but also offers tremendous antibiotic properties to protect hippos from harmful bacteria when they’re in the water.
In theory, when the hipposudoric acid (red) mixes with the milk (white), it produces a pink solution. But there is actually no evidence to suggest that this ever happens.
07. Relativity and Einstein
★ Einstein wasn’t the first to coin the term relativity. Galileo Galilei and Sir Issac Newton first gave the concept of classical relativity. Now the word Einstein is synonymous with genius.
