As seen in "MythBusters: Duct Tape Hour 2"
DCL

Finding: BUSTED

Explanation: MythBusters Kari Byron, Grant Imahara and Tory Belleci confirmed that duct tape could hold a vehicle together and keep it running. But when fans asked them to test if the brawny adhesive could halt a speeding car, the team stretched duct tape's legendary strength to its limits.

Using only a single roll of tape, the team constructed the thickest barrier possible stretched between two rails, per viewer request. Not surprisingly, the car travelling at 40 miles (64.4 kilometers) per hour broke through the gray finish line with ease. After all, the car constituted 300,000 pounds (136,077 kilograms) of moving force.

However, not even 100 rolls of tape forming a 3-inch-thick (7.6-centimeter-thick) blockade could stop the car in its tracks. The MythBusters may have proved that duct tape can fix, lift and trap a car, but the busted myth finally put the brakes on duct tape's superb sticking power.
