Plastic is a type of polymer, or a chain of atoms and molecules. That chain pattern gives plastic some amazing abilities! They are flexible because the chains of atoms can be twisted or turned in many different shapes, sometimes even when the object is a solid! It is moldable (or easy to twist into different shapes) because when the polymers get hot, they start to separate. When the material cools down, the atoms settle down in chains of atoms again. The chain-like structure of polymers help the material have more strength. The twisted shape allows more atoms to be present. That makes the object more dense, which makes the material strong, flexible, and moldable. Since they are string, moldable, and at the same time lightweight and flexible, plastic is used in a lot of things in everyday life such as cars and even computers!
