From SurvivorFever:
"The Final Four Immunity Challenge will test the Survivors' balance and accuracy. Each tribe member will stand on a very small perch at the top of a 20-foot pole in the water.
When the game begins, they will lower a bucket into the water to fill it, then pour from the bucket into a very narrow bamboo shoot. As the bamboo shoot fills up with water, it will raise a flag.
Once the flag is high enough to reach, they must carefully grab it and raise it above their head."
