Tunnel Swim; Eat Balut; Bike Plank

Stunt #1: Tunnel Swim Contestants would have to swim though an underwater tunnel that was 80 feet long. Along the way, there were four air pockets. The two men and the two women to get through the tunnel the fastest would advance to the next round. The others would be eliminated. Stunt #2: Eat Balut Contestants would have to eat two balut eggs, which are soft boiled eggs with an underdeveloped duck embryo inside. Everyone who ate their two balut eggs in three minutes would advance to the finals. Stunt #3: Bike Plank Contestants would have to ride a bike across a 12-inch wide balance beam suspended between two rooftops over 120 feet high. The contestant to get across the beam the fastest or get the furthest before falling would win the $50,000.
