Did you ever stop to think of how are the plastic bottles for your water, soda or whatever being made? It's pretty interesting! There are special types of machine,'Automatic pet blowing machines' to make bottles we use in daily life. This wonder of the machine to small pieces of plastic, and bottles in their different permutations come out! Should be it like magic, but no is really the science and technology in action!

Well, what is a small piece of plastic? Well, it is called a preform. A preform is a small test tube-lookalike, that is made from PET (Polyethylene Terephthalate) which doesn't change shape easily. You see, this plastic is great for being both durable and mouldable! The preforms then undergo an interesting procedure to create bottles. They are soften initially They are then filled with air as puffball and increases in size like a balloon. After freezing, they are allowed to cool making the bottle hard. It is these little plastic pieces that the automatic pet blowing machine can turn into bottles we see and use every day like water bottle, soda bottles etc.
