Saun Dann leaves Attichitcuk with his mind evaporator

A mind evaporator, also known as a proton chair, was a device used to stimulate the mind. It could be used for either serious or entertainment purposes.


The machine consisted of a large chair that the participant would sit in and a helmet attached to the chair that would cover the subject's eyes. A cassette could be inserted in order to begin the program, and the user would enter virtual reality. The mind evaporator was powered by a proton pack. It is not known whether the device could work on droids.


Attichitcuk used the device to aid in training for flight of the Oevvaor jet catamaran during the Clone Wars. Utilizing its virtual-reality capabilities, he was able to hone his skills in order to participate in battle at his advanced age. This training proved useful at the Battle of Kashyyyk.

He also used the device as entertainment. He viewed holograms of Human girls singing and dancing on the machine. One such girl he viewed was Mermeia in 1 ABY.

Behind the scenesEdit

The Star Wars Encyclopedia defines the device as:

"Mind Evaporator (Kashyyyk) - Basic translation of a Wookiee term for any addictive video game that lacked any form of educational purpose."

According to some of Brian Bartholomew's blueprints for various props in The Star Wars Holiday Special released on its 30th anniversary, the mind evaporator was made up of a purchased chair, with the "proton helmet" being made of a hairdryer connected to a plastic accordion hose (such as one belonging to a vacuum cleaner), as well as a heavy cable with sockets. The earpieces were made of clear plastic glasses or another unknown component, the latter having wheat-lamps or pilot lamps twinkling randomly (though the rest of the earpiece is opaque), three extra control knobs below the earpieces, and a socket plate on the back hood; as well as having planted-on rivets as well as enameled clear visors. The evaporator controls on the arm portions of the chair were made of a Pearlcorder that would be used to play the cassette tapes. In addition, on the back of the chair were various plastic model kits and dummy doors, as well as a vent and planted-on clear plastic multimeter measurements by Olson Electronics.[1]
