The time travel chamber, built from a 1952 Sears Coldspot refrigerator
Coldspot was the brand that Sears used for their line of electric refrigerators from 1928 until 1976, when Sears began to sell their refrigerators under the Kenmore label instead.
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, Emmett Brown finished his time travel chamber, which was a time machine built from a 1952 Sears Coldspot refrigerator.
Behind the scenes
- A refrigerator was the original idea for the time machine. Bob Gale and Robert Zemeckis changed it to a DeLorean DMC-12 due to concerns that children might attempt to copy the events on-screen, and end up locking themselves in refrigerators.
