Time travel chamber

A 1952 Sears Coldspot converted into a time machine.

Sears is a chain of department stores with mail order service from which residents in rural areas such as Hill Valley relied on to order almost any household item.


In 1955, Sears had four-year car batteries on sale for $14.95, but were too much for the Peabody family to pay, and also sold television sets.[1] Dr. Emmett Brown bought Marty McFly a full outfit and Vaseline hair tonic from Sears to blend in.[2] George McFly had bought attire there in 1981 that he still wore in 1985.[3]

In 1983, in the alternate timeline where an elderly Biff Tannen traveled from 2015 to 1955 with a sports almanac, to make his younger self rich, Doc finished his time travel chamber, which was a time machine built from a 1952 Sears Coldspot refrigerator.
