Finding: CONFIRMED

Explanation: MythBusters Jamie Hyneman and Adam Savage required not one — but two — episodes to test the full range of duct tape's legendary properties. During the second round of duct tape tales, the duo dared to take the tape's tensile strength to new heights by erecting a 100-foot-long (30.5-meter-long) bridge out of the sticky stuff.

It took 196 rolls and nearly 400 pounds (181 kilograms) of duct tape to complete the MythBusters' bridge design. Jamie and Adam twisted long strips of tape into cord-like strands, weaving together more than 10 layers of them to construct the walkway portion of the bridge. Modeling the overall shape after a rope bridge, the duo molded handrails and suspension ropes out of duct tape to finalize a structure that stretched 50 feet (15.2 meters) above the ground.

Stepping lightly, Jamie and Adam traversed the sticky territory one after another without breaking through. Neither volunteered to stroll across the duct tape bridge again, but one successful pass was all it took to cross the confirmed myth off their to-do list.
