Why is Coca Cola called Coca Cola?
Coca – cocaine. Pemberton called for five ounces of coca leaf per gallon of syrup, a significant dose; in 1891, Candler claimed his formula (altered extensively from Pemberton's original) contained only a tenth of this amount.
Coca-Cola once contained an estimated nine milligrams of cocaine per glass.
Why was Africa called 'the dark continent'?
For long time, the Europeans were unaware of the existence of a continent called Africa!
So, when they first discovered and explored the continent, they called it by the name, 'the dark continent'.
Actually, one of the world's oldest civilizations flourished on the banks of the Nile more than 5000 years ago.
But, the rest of the world had little knowledge about the interior of Africa for a long time, and hence the myth of 'the dark continent' came into existence.
