interesting facts of science
Most people understand coughing and sneezing can spread germs that cause illness, but the speed and distance they can travel might surprise you. It is found that the average sneeze or cough can send around 100,000 contagious germs into the air at speeds up to 100 miles per hour.
2. People are taller in the morning than in the evening.
The spine compresses during the day with the weight pushed down on it. During the night it expands again, as lying down takes the weight back off. Depending on your height, you gain/lose a few cm during this process.
3. There is enough acid in the human digestive system to dissolve a razor blade.
Hydrochloric acid in your stomach is some strong stuff. While your blood has a pH of around 7.4, your stomach acid has a pH of 1 to 2. That means it is a strong acid indeed and it will do lot of damage.
4. Smelling or tasting through foot ?
If you rub garlic on the bottom of your foot, it would be absorbed through your skin and eventually your breath will smell of garlic! Your skin has oily and watery layers, which makes it good at protecting you from outside molecules. However, garlic contains a molecule called Allicin, which has properties of both water and oil. Because of this, it can permeate the skin in your feet and travel through your blood all the way to your mouth and nose.
5. Your brain gets lighter as you get older.
In your twenties, it starts to lose up to a gram (0.035 ounces) a year as cells die and are not replaced.Like the rest of your body, your brain changes with each passing year, we begin losing neurons—the cells that make up the brain and nervous system.
6. The hair of really intelligent people contains larger quantities of the minerals copper and zinc than the hair of less clever people.
There are several researches made on this. I recommend you google for it if are really keen to know more.
7. Body Farm
A ‘body farm’ is a research center where dead bodies are left to decay in various situations. Scientists study their decomposition and the information is used to help police with murder investigations.
8. Some substances color your urine.
Beets, berries and fava beans are among the foods most likely to affect the color.If you eat lots of rhubarb, your urine will be orange, and blackberries can make it go red!

11. Deadly Water
Drinking TOO much water can be bad for you. It is possible to die from drinking too much water. Water intoxication and hyponatremia result when a dehydrated person drinks too much water without the accompanying electrolytes.
12. Heavy Weight Ants
Ants are capable of carrying objects 50 times their own body weight. Relative to their size, ant muscles are thicker than those of larger animals or even humans. This ratio enables them to produce more force and carry larger objects.
13. Super fluidity in Helium
When Helium is cooled to almost absolute zero (-273°C), the lowest temperature possible, it becomes a liquid and it flows against gravity and will start running up and over the lip of a glass container!
14. It once rained fish in a small town in the Australian outback.
There have been numerous reports of spiders, fish, frogs, and other animals “raining” from the sky. Scientists think the most reasonable explanation for such events is animals being sucked up and transported by waterspouts or other tornadic winds.
This is the short list of 15 things which I think is a bit unusual when knowing for the first time. I hope you will keep on adding some more on the comment section.
