An underground city

Coober Pedy is a small city in Australia, with a population of about 3.500 citizens. It is famous for two reasons. The first and important reason is the production of opal, a type of precious rock found in abundance in the region. The mining area is responsible for 70% of the global production of opal. 

The second reason why this city is famous is the fact that its citizens live underground. It is a habit that began in the beginning of the 20th century when the first miners who settled there lived in mines and caves in order to avoid the extreme summer temperatures of the Australian desert. 

Today this situation has become a way of life for many of them who live permanently in the city. Temperatures normally reach 40 degrees Celsius, whilst the highest temperature recorded is 47 degrees Celsius. This is the main reason why the underground houses have become more and more popular, where conditions are more stable. 

These are constructed by specific companies in undertaking the underground homes and the cost is similar to that of building a normal (overground) house. There are also several museums, shops, churches and hotels, all located underground.   

The obese nation

Nauru is the worlds smallest island nation which is located in the South part of the Pacific Ocean. The islands is 21 sq.km. and has a population of about 10000.

 It has a negative record, of being the most obese nation in the world. 97% of men and 93% of women are considered overweight and obese. This of course has disadvantageous results for their health, whilst diabetes, cancer and heart problems are common.  

The population of the Republic of Nauru is addicted to fast food in such an extent that fresh fruit and vegetables are not found on the island. This is an immediate result of the modern western way of life, which the people in the small island wish to follow. Be that as it may this was not the case during previous decades. This is evident through countless pictures from the past that show how people were fit and athletic.  

Nonetheless they are currently fans of weightlifting in such an extent that the World Championship took place there. 

Mona Lisa made by coffee cups

Everyone knows and can easily identify this Leonardo Da Vinci painting. The unique fact is that in Australia they achieved to recreate this painting using 3604 cups of coffee. They achieved this by filling with different quantities of coffee the cups they had and by using more or less milk in each one to change the colour.
