Two porcelean balls (in vibrant colors: red, blue, yellow, green, purple, orange or black and white) attached to a string hanging from a stick. To operate this toy, the happy little child would swing the stick in a circular motion, causing the balls to click together... resulting in a rapid beat that would drive kids wild and parents out of their minds!! Ka-bangers were quickly taken off the market because a lot of kids got lobbed in the head or knocked out their teeth while playing with them. My mom never let me have a set of ka-bangers. To this day I still want 'em, more than ever!!
