Do you know why clothes looks darker when wet? Or why do bruises change their color? Do you believe that there are immortal creatures on our planet? If you want to know the answers, this article is for you.
#1 A piece of paper is larger that the observable Universe
Though it seems strange a piece of paper can be larger than the Universe. If you fold a large piece of paper 90 times it can reach the Sun and if you sit on it you can admire the space.
#2 Why is snow crunchy?
Snow consists of ice crystals. When you step on snowflakes they break and produce that crunchy sound. However, if the temperature is near the zero the snow doesn’t crunch while the surface of a snowflake contains more water.
#3 Why do wet clothes look darker?
Water makes a tiny layer on fabric that becomes an obstacle for the light. So the light can't reach wet fabric as fast as dry one.
#4 Why is a piggy bank piggy?
In the middle ages, people used cheap pygg, a type of clay, to make pots for money storage. These pots were called piggy jars and used to keep the money. In the 18th century, the term 'piggy jar' was changed to the 'piggy bank'. In 19th-century Europe, piggy banks were made in the shape of a pig.
#5 Why do bruises change its color?
A bruise is formed when capillaries under the skin are damaged and the blood leaks out of them. At first, a bruise is red. Then it darkens because of low oxygen supply. In 5 days a bruise becomes green due to haemoglobin breakdown. In 7 days it becomes pale and soon disappears.
#6 There are creatures who can live forever
They exist! The Turritopsis nutricula, a tiny 5 mm long jellyfish, can transfer its cells to their earliest forms and thus can become immortal.

You totally lost me on the piece of paper being larger than the observable universe.
The meaning of this was not explained at all!
Rich Davis
I think the paper one relates to the fact you cannot fold a ‘letter’ sized sheet of paper more than 7 times. But if you had a large enough piece of paper and folded it 90 times it would be as thick as the distance between earth and the sun! My 2 cents.
Joseph Faiers
Had to think about the paper one.
But got it eventually. :)

I agree Jenna Hull, the paper theory doesn't make sense a it's not explained very well.
Judy Wilson
I don’t get the logic of the piece of paper??!!
William R. Meredith
jeana hull, made no sense
Elsy O. Stromberg
The paper one doesn't make sense, but the others are interesting.

How is known that paper folded 90 times reaches the sun. No one has ever been to the sun much less taken a piece of paper there.

jeana hull, a physical impossibility, but a mathematical novelty. Take a small number, like the width of a piece of paper, and double it. Then double it again - 90 times - and you have a phenomenal number...

Rich Davis, while looking with the bare eye, right?
Julie Domaille
I don't get the 'folding paper' theory. Is not true that sponges can reform even when liquidised does that make them immortal?

jeana hull, You cannot fold a piece of paper 90 times.If you could the length will reach the sun. just try with a standard paper.

Interesting facts and ideas, both enriching and enhancing knowledge and enlightenment. Please don't ever stop - hoping you never run out of materials. Thank you so much.

Looks like this is an old question, recycled with no new information on the paper theory. Also, I’ve walked on snow at 0°- it still crunches.

Next quiz please, and lay off the LSD.

Ok, even if we had a piece of paper that could reach the sun from here on earth, that is in no way of even remotely being larger than the whole universe!, sorry!!
