Does the color red really make bulls angry?
To confirm the invalidity of this myth, the MythBusters set out to find a way to test it. They decided to put makeshift matadors into an arena, each holding a flag of a different color, and wait for an angry bull to see red. The red, blue and white flags got equal, half-hearted attacks when they were motionless. In order to elicit an aggressive charge response from the bull, the flags had to be waved.
