Stunt #1 (Water-tube escape) The ladies would be trapped inside a plastic box and lowered into the water. With an air pocket at the top, they would have to swim to the bottom of the box, turn two wheels to drop the bottom out of the box, escape, and swim to the surface. The four ladies to do this the fastest would advance to the next round. The others would be eliminated. Stunt #2 (Box of Reptiles) Going two a time, the ladies would be seated in a Plexiglas box of boas, pythons, and geckos. While in the box, they would have to use metal rods to transfer magnetic disks from slots in the bottom of the box to slots in the top of the box. They lady in each race to transfer 5 magnets first would advance to the finals. The loser of each race would be eliminated. Stunt #3 (Wind tunnel) The ladies would have to walk through a Plexiglas wind tunnel and collect flags as a fan blew wind and water through the tunnel at 100 miles per hour.
