The Calvin and Hobbes Wiki

The Cerebral Enhance-O-Tron is an invention made by Calvin. Its purpose was to enhance one's brain. It was used

Cerebral Enhance-O-Tron

to enhance Calvin's brain when he was writing a report about Tyrannosaurus Rex being a "fearsome predator" or a "loathsome scavenger". The effects might wear off when the user goes off task, as he says he will make illustrations of a T-Rex eating people in the Natural History Museum before writing the report thus going off task and returning to normal.

Appearance and effects[]

Like many of Calvin's inventions, it was made from a cardboard box, but with a colander connected to three wires. The wires served as input and output wires, and the third was a grounding string, which Calvin called "a lightning rod for brainstorms", so as to keep one's ideas grounded in reality. The colander served as a thinking cap to enhance Calvin's brain. As a side effect, Calvin's head swelled. The effects of this were temporary, however.
