"One tribe member must race into the ocean to fill a bucket with water. Then they must bring it back and toss it to a tribemate. The bucket must be tossed twice more, and the final tribe member must catch the water itself in another bucket, and use it to fill a jar. The tribes must repeat this until they have enough weight in their jar to lower it to the ground, sending a lit flame up to a fire tower. First tribe to light their fire wins reward." ~ @SurvivorWiki
