| Liquid nitrogen is injected into a highly insulated chamber in which molded rubber parts are tumbled and blasted. When kept at sub-zero temperatures, the liquid nitrogen stored at the bottom of each cryovat turns into a frigid vapor. amp;nbsp; Such a trust is set up to last hundreds of years—perhaps indefinitely—to benefit a dead person who has been frozen in liquid nitrogen using a process called cryonics. |
