They're designed to capture...and often kill. But they don't always harm their prey; traps are often necessary to the survival of a species. Modern Marvels "Traps" is the exploration of a device as old as humanity itself. We'll trap 400 lbs. Black Bears with West Virginia Division of Natural Resources biologists. Then we'll trap, neuter, and release dangerous feral cats left stranded in New Orleans after Katrina. Mouse traps? We've got 3000 of them. We'll set massive, cast iron jaw traps from history - don't try this at home! We'll head underwater to see how giant screw traps count salmon on the Columbia River. Man traps? We'll see a high tech version that any James Bond villain would lust after. Gotcha!
