Don't eat that.

Do you know that black chocolate is made by something that it's not good to eat?
A group of scientists discovered last month that one variety of that hard chocolate is made by a mixture of wet sand and droppings from a big variety of animals that are living in a farm in Africa. Some workers of the farm collect all the droppings every week and they send it to a laboratory in Sweden, where all the good chocolates are made. In Australia, there's another farm where they collect wet sand to mix it with the droppings so, after they collect it they send it to the same laboratory in Sweden.
When all the ingredients are collected they put it inside a machine which mix everything and make little figures of a pig with that "chocolate".

The scientists haven't discovered yet which is the ingredient that gives the good flavour to that strange chocolate but they have banned it around the world because it causes too many stomach pain and the farmers are in process of judgement.
Luckily, nobody died because of the chocolate.
