How old is your egg ?

How old is your egg ?

 If someone asks how old an egg in your refrigerator is, 

you'll probably feel embarrassed.

 however, here is a way to tell the freshness of an egg.

 Take a container full of water and put the egg in it.

 A very fresh egg will sink to the bottom and lie horizontally.

 A week-old egg will stand upright. After 4 weeks,

 the egg will float and should be thrown away.

 What makes the egg to sink or lie tilted?

 A very fresh egg has little air inside it, so the egg doesn't float.

 As the egg gets older, the amount of air inside it increase, and 

this allows the egg to float.

 In a fresh egg,

 the white part will be thicker, making the egg ideal for boiling and frying.

 After a week, 

the white part becomes thinner and easier to separate for making cakes and creams.

 In 2~3-week-old eggs,

 the yellow part spreads out and the white part becomes more fluid.

 These are good for baking bread or making sauces, 

when the appearance is less important.

Raise Dirty water ?

Raise dirty water.

Would you pay a dollar for a bottle full of dirty water?

What if it was labeled "malaria" or "cholera"?

You could buy this unusual bottled water from a vending machine during World Water Week in New York City.

It is one of the most populous and crowded cities in America.

The water was sold as part in many areas of the world.

The fact is, thousands of children die from water-related diseases every day, 

and millions more have no clean water to drink.

Most New Yorkers who passed by the vending machine were disgusted by the bottles of dirty water at first.

But

once they learned more about the serious problem, many of them donated money
to help end it.

The fundraiser was organized by the charitable organization UNICEF.
They promised that each dollar would allow them to provide fresh, clean water to 40 children for one day.

It may seem raise money like a shocking way.

but UNICEF's innovative method was extremely effective.

It's an amazing idea!!
