No, not decomposed in nature. Clean burning though in waste ovens.
It takes 1000 years for it too biodegrade and that is if it is buried. :)
Polystyrene (foam): -0.04 oC/sec weights of polystyrene cup: 113.8g thickness of polystyrene cup: 0.1mm
When the pin is pushed into the cup the polystyrene (Styrofoam) is temporarily pushed aside. When the pin is withdrawn the polystyrene reforms largely to its original location. If a drill was used, the same diameter as the pin and material was actually removed the cup would leak. Also the water tension of the water in front of a hole the size of a pin would prevent the water from leaking out.
The polystyrene cup is a better insulator than metal, metal is a good conductor of heat and so would transfer the heat from the reaction to the air outside it, where polystyrene keeps the heat inside. This enables you to get a much more accurate reading, as less heat has escaped.

Polystyrene (especially the expanded "Styrofoam (R)" type) is a good insulator. Metals are good conductors of heat.The insulating cup will maintain a greater heat differential than the conductor so if there is a liquid in the cup that is at a greater temperature than the surroundings, the metal cup will loose more heat than the polystyrene cup.
