| All you need to do to use the Crystal Ball is to ask a yes/no question then to slightly shake the breadboard that contains the display, and you will hear a sound which indicates that your question was answered, this is possible due to the tilt sensor, meanwhile a thematic song is running in the background and the LEDs would flicker during the entire functioning of the toy. | All you need to do to use the Crystal Ball is to ask a yes/no question then to slightly shake the breadboard that contains the display, and you will hear a sound which indicates that your question was answered, this is possible due to the tilt sensor, meanwhile a thematic song is running in the background and the LEDs would flicker during the entire functioning of the toy. | ||
