Little-known interesting scientific facts
Now is the time to awaken the brain with a set of interesting scientific facts. These small facts are based on science and will be very new to some readers.
1. Raindrops are not in the shape of teardrops, as you often see on drawings. It is actually spherical.
2. When does something skip the liquid state from the solid and directly sublimate to the gas? When you throw dry ice into the fire.
3. Gorilla sleeping in the nest? They woven together the soft leaves and branches of the tree to build a nest. Male orangutans like to sleep on the ground, while female orangutans like to sleep in nests built on trees.
4. Champagne does not foam because of the presence of carbon dioxide? Foaming is due to stolen goods or dust. In a glass cup with a very smooth surface, no dust molecules are attached to the inner wall, and champagne will not foam at all after pouring.
5. Most digestive exercises are not done in the stomach, but in the small intestine. This may be the reason why some obese people can still overeating.
6. Is the red juice oozing from the raw steak not blood? That is blood myoglobin. When the steak entered the sales market, almost all the blood was drained.
7. Plastic bags are more environmentally friendly than paper bags. The production process of paper bags consumes more energy than plastic bags. The recycling of paper bags is also more energy-consuming than plastic bags, and paper bags take up more space in landfills. Because landfills are usually below the surface, paper and plastic are difficult to biodegrade in closed conditions.
8. Polar bears are very cute animals. Their hair is transparent, not white, and their skin is black or white. In a warm and humid environment, their hair can change from seaweed color to green.
9. Pet allergies are usually not because of fur, but because of dead skin, saliva, or stolen things. Cleaning your pet regularly can greatly reduce allergies.
10. Is the tongue map a lie? You can taste various flavors with different parts of the tongue. The tongue map comes from a famous German newspaper in 1901.
11. When you put the shell in your ear and listen to the sound of the sea, what you hear is actually the blood flowing in your own blood vessels! You can use any cup-shaped object to hear this effect.
12. When you are alive, your brain is pink. When you die, it turns grey. When we describe the brain as "gray matter" and "white matter", this expression of color is not accurate.
13. Mercury is a charming liquid metal, but it is not the only liquid metal. Gallium is solid at room temperature, but it melts when placed in the hand. Cesium (Cs) and francium (Fr) are the second rarest naturally occurring elements. They can also exist in liquid form at or near room temperature.
