"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.. ------------------------------------------------------------------------- --
