A strip of UHMW PE is heated and gradually stretched over 180 °C., the melting temperature of PE, the polymer chains coil up again causing the film to shrink. Again heating to 120-136 °C an attempt will be made to stretch it. (Related topic: polymers) |

Cooper pairs. Putting one ball bearing (the "electron") resting on a rubber sheet (the "lattice") will cause it to stretch creating a depression in which the ball sits. Another ball placed near enough to the first causes there to be a coupling between them that would otherwise not be there without the rubber sheet. From the TLP Superconductivity |

Cooper pairs. One ball makes a depression in the rubber sheet and moves on. A second ball rolls into the well and become effectively bound to the first ball. From the TLP Superconductivity |
