An automobile airbag takes only 40 milliseconds to inflate after an accident.
At the center of every chlorophyll molecule, in every green plant, there is a magnesium ion.
White surfaces reflects all the radiations that fall on them. As test matches are played for several days the cricketers are exposed to the sunlight for a long time. White clothes keep their bodies less heated as they absorb minimum amount of heat.
Cricketers from different countries have their own unique clothes with different colours. But they all wear white clothes when playing in test matches. Do you know the reason?
A day on the planet Mercury is twice as long as its year! Mercury rotates very slowly but revolves around the Sun in about 88 days.
Mosquitoes are responsible for the largest number of human deaths by any animal species. They are killers of over 2 million people a year.
Scientists have now discovered that gold is formed during earthquakes. A less concentration of gold is dissolved in ground water (1 ppm)
When an earthquake happens, water vaporizes instantly leaving gold deposits.
The average diameter of a carbon nanotube is one nanometer.
In other words,thickness of 10 million nanotubes lined one next to the other, will be just one centimeter.
Almost all the hydrogen atoms in our bodies were created in the Big Bang that occurred over 12 billion years ago.
Most of the world’s snakes are non-venomous.About 500 snake species are venomous,and of them only about 30-40 are harmful to humans.

It takes up to 50 million years for the energy produced at the core of the Sun to reach its surface.
If the Sun were to stop producing energy today, it would take 50 million years for significant effects to be felt at Earth.
A special layer called Tapetum Lucidum found in cats eyes,reflects the light back.This is located behind the retina. The light that falls on retina,also falls on this layer and gets reflected. The reflected light increases the brightness inside the eye.This gives them night vision ability.And this shine makes their pupil glow in different colours.
When we direct a torch beam to the eyes of a cat or a dog in dark, they illuminate giving a Red,Green or Blue shine. We can’t see such an observation in humans. What is the reason behind this?
Marie Curies research papers are still highly radioactive and to access them you must sign a waiver and wear protective clothing.
Richter scale was developed in the 1930s as the method of measuring the magnitude of earthquakes, in terms of energy released.
Cats have powerful night vision.The intensity of light they need for vision is six times lower than what a human eye needs to see.
Because of the moonlight, snakes find it is hard to hunt at night,as they are more visible to the prey. The snakes remain in hunger, for the days moonlight appears brightly. Their venom glands contain much venom collected , and an attack on such a situation will create very harmful conditions than usual.
