流言終結者：再探萬能膠帶 (Duct Tape Hour 2) 第144集

單元：　膠帶的102種用途 (102 Uses for Duct Tape): 膠帶橋(Duct Tape Bridge)
、汽車修護(Duct Tape car fixed)、攔車膠帶(Car Stop)

在本集的流言終結者，準備好再次體會膠帶的神奇魔力。亞當和傑米挑戰極限，並且
冒險玩命；他們嘗試橫越裂溝，走過一條用膠帶搭的橋。另外，凱莉、格蘭和托瑞上
路，測試膠帶能否保護車身不致散成碎片；車子一路衝到終點，測試黏黏的膠帶能否
攔住高速疾馳的車子。

…build a usable bridge across a chasm. "Confirmed"
Adam and Jamie began by applying force to the middle of a strip of duct
tape in order to determine its breaking strength. Finding a result of
67.3 lb (30.5 kg), they built up strands from layers of tape and Adam
experimented with weaving them together to strengthen the design. They
settled on a rope bridge with a 10-layer walkway, two handrails, and two
stabilizing rails.
They took the bridge to Mare Island Naval Shipyard, where they could set
it up across a 104 ft (32 m) gap with a 50 ft (15 m) drop. During test
runs to pre-stretch the parts and remove the tape's elasticity, they
decided to connect the walkway and handrails with struts in hopes of
reducing the wobble. A total of 196 rolls of tape were used to build the
finished bridge, which was connected to steel frames on opposite ends of
the gap. Adam and Jamie both made the crossing successfully, though Jamie
had a much harder time keeping his balance due to his fear of heights
and/or the stress of Adam’s previous crossing. Jamie commented that the
elastic nature of the tape made it a poor choice for building bridges.

…hold a completely dismantled car together so that it can be safely
driven at high speed. "Confirmed"
Kari tore apart a car’s body and frame with the help of a squad of San
Francisco firefighters. Grant and Tory then reassembled it with tape, and
the Build Team took it to Naval Air Station Alameda, where they set up an
obstacle course on the runway to put as much stress on the car as
possible. With Kari driving 40–60 mph (64–97 km/h), the car held
together through 10 laps. Next they did some off-road driving in the
rain; the engine stalled after several minutes, but the tape did not fail.

…hold a car in place. "Confirmed"
The Build Team hooked a force meter between a car’s rear bumper and a
telephone pole, and found that the car could pull with a force of 1,300
lbf (590 kgf). Based on the breaking strength data from the bridge
testing, they wrapped five rolls of tape around the car and pole to bind
the two together. When Grant stepped on the gas, the car stayed in place
even as the tires began to smoke, with only one strip of tape breaking.

…stop a car going 60 mph (97 km/h). "Busted"
The Build Team placed two concrete barricades on the Alameda runway and
used one roll of tape to make a single thick strand strung between them.
Driving at 40 mph (64 km/h), Tory was able to break through easily. For
further tests, the team used 100 rolls of tape to make a 3 in (7.6 cm)
thick wall, which they hung between the barricades, and towed the car
into it while Grant steered remotely.
On the first test, a problem with the tow cable caused the car to hit one
of the barricades; the tape took a glancing blow, but did not break. The
second test ended with one of the wall’s anchor points breaking loose,
while the wall itself remained intact. In the third and final test, the
car hit the wall dead center and broke through, but not before the tape
had stretched nearly 6 ft (1.8 m). Based on the amount of time and
material that would be needed to construct a workable car stopper, the
team declared the myth busted.
