To raise the disco ball near loot lake in Fortnite Battle Royal, you and 3 other players have to dance at the same time on the four dance floors in the west building near the lake. The disco ball in the middle will start to go up slowly once all 4 players are dancing.
You can try this in solo as well as duos and squads. If you are lucky everyone will have the same goal and help each other out to finish this challenge.
