Blood vs. Water
Operation Balance Build is a recurring challenge of Survivor.
The castaways have to attach a small wooden bowl to a prong at the end of a long pole to maneuver it through a metal structure. The structure is mounted on a spring in order to increase the difficulty. Once they have the piece through the structure, they have to sit it at the top. First castaway to stack all ten bowls on top each other win.
In Survivor: Blood vs. Water, the challenge was the first Redemption Island Duel, between Candice, Marissa, and Rupert. Candice and Rupert were close to finishing the Duel when Rupert's stack toppled over. Candice cruised to finishing first, while Rupert was unable to recover, allowing Marissa to continue on.
