"TDR"

I am very excited about what is going to be my 'Treball de recerca'. It is about diferents coke drinks and some of their propieties and I think it will be really funny to know. I particularity like coca-cola but I  want to know what was the history and the components and also what is considerated better for health and people. The practize part will be to extract cafeine and other substances so let's work!
