Colosseum: Roman Death Trap  

Archaeologists and engineers employ ancient Roman techniques to build a 25-foot lifting machine and trap-door system similar to those used in the Colosseum, where ancient texts claim wild animals emerged, as if by magic, from beneath the floor to attack gladiators and people condemned to death. In this instance, the team releases a wolf into the ancient arena for the first time in 1500 years.
