"Cry is free" is one constantly used sentence for users who are complaining about something. But what most don't know, is that this sentence is actually a huge lie.

As far as we know, tears consist of water and 0,9 grams of salt per liter. And both of these ingredients are not free.
Here I listed the price for 10 liters of tears for the countries of the G8. I used the following formula (price is in US Dollars):
(Price 100 gram salt/100)x9 + (Price 1 cubic litre water/100) = Price for 10 Litre Tears

France: 0,20 $
Italy: 0,17 $
Germany: 0,19 $
United Kingdom: 0,22 $
USA: 0,18 $
Canada: 0,18 $
Japan: 0,18 $
Russia: 0,16 $

That means Russia has the cheapest cry.
