Why do rubber bands last longer refrigerated?
The rubber band actually expands when it gets colder! This occurs because of the unusual polymer structure of rubber. When the long chains get hotter and vibrate, they actually shorten, causing the material to contract. When the chains cool down, they relax and stretch out, causing the material to expand.
What is an Isrefrigerator?
A refrigerator is a machine used for keeping things cold. It is sometimes called a fridge or an icebox. People put food and drinks in it, to keep those items cold or good (unspoiled) for a longer time. A refrigerator has a heat pump which takes heat away from the air inside the fridge.

What kind of plastic is used in fridges?
ABS, polypropylene and polystyrene are all used to form the fridge’s interior, including the interior door and wall panels as well as the shelves and drawers. Polyurethane is primarily found in refrigerator insulation, forming thin strips that trap air between layers of harder plastics.
