盡方法驗證有關動量的流言，他們想瞭解在前進時把物體往後拋出，物體是否真會垂
直落地？
本集要驗證兩個流言：電影裡間諜車往後方灑雞爪釘、灑油及釋放煙幕的方法真的有
辦法甩開追逐的車輛嗎？在向前行駛的車輛上向後丟出同速率的物體會以垂直軌跡落
地嗎？

-------------------------------------------------

...road spikes or tacks. "Busted"
While the road spikes managed to puncture the pursuit car's tires, they
did not instantly deflate and the pursuit car managed to catch Adam. The
reason why the spikes failed was attributed to the fact that the spikes
stuck in the tires, partially plugging up the holes and causing the tires
to deflate more slowly.

...a smokescreen. "Confirmed"
During the first run, Jamie attached several smoke grenades to the rear
of his car to create a makeshift smokescreen. While initially successful,
the smokescreen quickly backfired when the smoke was sucked into Jamie's
car as well, blinding and choking him and forcing him to stop the chase.
They modified the rig to keep the smoke grenades outside of the car, and
Adam became the driver while wearing a oxygen mask. The second test was
more successful, with Adam being able to use the smokescreen to elude the
pursuit car.

...an oil slick. "Plausible"
The pursuit car was slowed down significantly by the oil slick, allowing
Jamie to elude it. However, the pursuit car did not instantly spin out as
is popularly shown in movies.

...Jamie's specialized car stopping devices. "No result"
As part of the MythBusters' challenge, Jamie designed specialized
car-stoppers meant to get caught in the pursuit car's undercarriage and
slow it down. While they deployed successfully, the pursuit car managed
to stay on Jamie's tail, despite it taking serious damage from the
car-stoppers. While it did not help in the short run, the MythBusters
pointed out that they would have been successful if the chase had gone on
any longer.

...Adam's parachute rig. "Partially Busted"
As part of the MythBusters' challenge, Adam designed a rig that would
deploy a parachute and release it in hopes of blinding the pursuit car.
While the parachute successfully deployed, the pursuit car was able to
avoid it and chase down Adam, though it was said that if the parachute
had deployed at the correct time, it would have worked.

----------

Throwing an object off the back of a moving vehicle at the same speed as
a vehicle will cause the object to drop straight to the
ground. "Confirmed"
For their first test, the Build Team used a treadmill running at 10 mph
(16 km/h) to launch a weight off the back of a truck, and saw that the
weight was propelled 6 ft (2 m) away. Next, the Build Team repeated the
experiment, but had the truck driving at 10 mph, and the weight seemed to
drop straight down. They then repeated the experiment at 60 mph (97 km/h)
using an air cannon to fire a soccer ball. However, they couldn't get the
ball to drop straight down and decided to change their method of firing
the ball. They tested a soccer ball pitching machine and Grant's ball
kicking robot against the air cannon. In the end, they decided to stay
with the air cannon after finding out it performed the most consistently
among all three machines. The Build Team attempted the experiment again,
and after a number of tries, finally managed to get the ball to drop
straight down..
