Choose an area of ceiling that is open and accessible. Place it over the area where guests will be dancing or gathering.
Climb a ladder to access the ceiling. Screw the disco ball's motor case to the ceiling using the screws included with your disco ball kit.
Attach the ball to the motor case using the clip or chain that came with the kit.
Flick the switch on.
Set up a spotlight across the room focused on the disco ball. Adjust the light so it hits the ball toward the center, creating a good spray of twinkling light.
Turn off the room lights to fully enjoy the disco ball effect.
