The fabrication of carbonated drinks consists of a 5 stage process. First of all, raw water undergoes a process of cleaning by flowing through a filter and right after being exposed to chemicals and water softener. The resulting liquid is pumped into electric heaters until the water boils and water vapour is mixed with another gas, carbon dioxide. Now, the mixture obtained this way is then turned back into liquid form in a cooling pipe, and later sent into what is called a Mixing Tank. This container enables the addition of new substances such as colouring, syrup or flavour conditioners, depending on the kind of carbonated drink being prepared. A new filter is placed at the exit of this last tank, already producing the final product, which needs to be properly transfered into bottles or cans. A final stage requires the packaging of the whole lot of bottles and cans and subsequently loading the trucks responsible for the transportation of the stack to the supermarkets.

Since the computer revolution that took place in the last decades of the 20th century, these machines have occupied nearly every aspect of current societies.

Nowadays, it is hard to find a job that does not need the aid of a computer, whether it is for information storing, mathematical calculations or work optimisation. It is therefore mandatory that young students, in order to be prepared for facing modern world issues, are totally capable of understanding and controlling computer programms. To achieve this, a classroom without personal laptops for pupils is no longer conceivable.

It has been proven that most subjects can benefit from a computer based learning, through the use of interactive apps, videos, etc. and most importantly, employing digital textbooks with considerable lesser cost, affordable by most public institutions, and no associated environmental problems like pollution or deforestation.

All these seem good enough reasons to transition from the traditional school system into this new technological one. However, one may also argue that children are everyday more in contact with computers since a very young age, and consequently do not need the presence of these machines in classrooms.

In addition, they may open the door for virtual learning from home, with pre-recorded lectures that would make most current teachers and school places close to needless, posing also a threat to socialization and collaborative working.

PC stands for 'personal computer', and very much so they tend to isolate us from the rest of the world. There is no longer the necessity to seek for help in wise teachers, for the internet is the wisest of them, and we have everyday uninterrupted acces to it.

In conclusion, I agree that computers at schools are undoubtedly necessary, but we should also try and find ways to diminish some of the threats they pose to the correct development of our youngest generation.
