Polymers Everywhere "Why do people care so much about polymers?" Polymers are everywhere. The plastic casing of your computer is made of polymers. In fact, all plastics are polymers! Where would you be without plastics! Good question. Look around your house and see if you can find a room without plastics in it! Now, not all polymers are plastics. Got that? All plastics are polymers but not all polymers are plastics. You know those gummy bears you had in your lunch today…they are polymers. So is the milk in your cereal, the cheese in your sandwich, the muscles in your arms and legs, and the DNA that makes up who you are! The pantyhose your mom makes you where on special occasion are made of nylon-another polymer. The silk in your best Sunday dress is also a polymer. Polymers are very important in the world of bioengineering and the medical sciences. People who have lost an arm or leg in an accident get special parts made for them so they can live normal lives. Much of the equipment used by police officers, fire fighters, and even astronauts is also made of polymers.
