Memory Foam Temperature Test
Warm foam recovers faster than cool foam.
Teaching & key ideas
What you do: Compress cooled and warmed areas.
What students see: Warm foam recovers faster than cool foam.
Why it works: Polymer motion depends strongly on temperature.
Question to ask: Why does the same foam behave differently?
