SUMMARY
The forum discussion centers on the behavior of rubber bands when subjected to heat, specifically using a hairdryer. When heated in air, the rubber band shrinks despite the expectation that heat would cause it to expand, as observed in hot water. This phenomenon is attributed to the material properties of rubber, which can undergo permanent deformation when heated in the presence of a weight. The discussion also references the concept of "heat shrink tubing" as a related example of this behavior.
