Did you know?

i wanted to post something really interesting, so..
Why is blue for boys and pink for girls?
In ancient times, it was believed that certain colors could combat the evil spirits that lingered over nurseries. Because blue was associated with the heavenly spirits, boys were clothed in that colour, boys then being considered the most valuable resource to parents. Although baby girls did not have a colour associated with them, they were mostly clothed in black. It was only in the Middle Ages when pink became associated with baby girls.
Why is the sky blue?
When sunlight travels through the atmosphere, it collides with gas molecules. These molecules scatter the light. The shorter the wavelength of light, the more it is scattered by the atmosphere. Because it has a shorter wavelength than the other colours, blue light is scattered more, ten times more than red light, for instance. That is why the sky is blue.
Why does the setting sun look reddish orange? When the sun is on the horizon, its light takes a longer path through the atmosphere to reach your eyes than when the sun is directly overhead. By the time the light of the setting sun reaches your eyes, most of the blue light has been scattered out. The light you finally see is reddish orange, the colour of white light minus blue.
Can anything survive after they freeze ?
No animal, once frozen solid (i.e., water solidifies and turns to ice) survives when thawed, because the ice crystals formed inside cells would break open the cell membranes. However there are certain frogs that can survive the experience of being frozen. These frogs make special proteins which prevent the formation of ice (or at least keep the crystals from becoming very large), so that they actually never freeze even though their body temperature is below zero Celsius. The water in them remains liquid: a phenomenon known as 'supercooling.' If you disturb one of these frogs (just touching them even), the water in them quickly freezes solid and they die.

i am full of with these unuseful informations :) so if u want to ask some, i would be glad answering. hope you enjoyed it.
