流言終結者：觀眾來找碴 (Mythssion Control) 第143集

單元：　撞車力道 (Crash Force)、 打掉你的襪子「再驗證」 (Knock Your Socks
Off Revisit)


在本集的流言終結者，一切由觀眾做主，儘管來找碴吧。首先，海納曼槓上了牛頓，
亞當和傑米要搞撞車大破壞，驗證傑米對牛頓第三運動定律的理解。另一方面，凱莉
、格蘭和托瑞繼續接受磨練，再次驗證「打掉你的襪子」，這次他們要使出終極重拳
。
觀眾們抗議傑米在「汽車夾夾樂」單元中作出的結論，他聲稱兩輛車以時速50英里（
80公里）對撞相當於一輛車以時速100英里（160公里）撞牆所產生的撞車力道，所以
他們將再次做出驗證。另外，觀眾們也提出了意見，表示流言終結者並沒有做出最佳
的驗證，如出拳方式錯誤、襪子的鬆緊帶太緊以及老兄不是自行站立。流言終結者將
再次做出驗證，並測試腿毛的影響。

Two cars crashing into each other at 50 mph will exert the same force as
a single car hitting a wall at 50 mph. "Confirmed"
In their small scale tests, the Mythbusters compressed clay with swinging
hammers at two different speeds (1x and 2x speeds). Their results showed
that two objects hitting each other at 1x speed will cause 1x damage. In
their full scale tests, the Mythbusters crashed two cars into a wall at
50 and 100 mph as references. They then had two cars going at 50 mph
collide into each other. After surveying the results, it was clear that
the two cars suffered damage identical to the car that crashed into the
wall at 50 mph. The Mythbusters explained that was possible through
Newton's third law of motion. Even though there was twice the force
generated from both cars, that force also had to be divided between the
mass of both cars as well.

It is possible to literally knock someone's socks off. "Partly Confirmed"
The Build Team tested various types of socks on both hairy and hairless
legs to see which sock could be pulled off the easiest. The Build Team
then concluded that a non-elastic woven wool sock on a hairless leg would
be the best possible combination. They then built ballistic gel legs
covered in lamb skin to simulate human legs. The Build Team tested
several punches: the uppercut, the right hook, and the body blow.
However, none of the punches managed to remove the socks, even with
superhuman strength. In order to see what it would take to knock a
person's socks off, they hit Buster with a girder mounted on a moving
truck. While the truck failed to knock Buster's socks off at 40 mph (64
km/h), they saw on reviewed footage that the socks were sliding off; a
second run at 65 mph (105 km/h) finally sent the socks flying off
Buster's feet. While the myth was confirmed, the Build Team pointed out
that they had to use an astronomical amount of force in order to achieve
it.
