"Busted" The Mythbusters first built a scale model of the slide, and discovered that the concept was plausible. They then built the full size ramp with dimensions based on thorough analysis of the video. For safety reasons, the Mythbusters built the slide next to a man-made lake (38.399581°N 120.995017°W) so that they could avoid injury if they missed the target. After several runs, the Mythbusters concluded that the 115 foot flight distance was impossible, as they could only travel at a maximum distance of 72 ft (22 m) with a peak speed of 30 mph (48 km/h). In order to achieve the 115 foot distance, they would need to be traveling at least 40 mph (64 km/h). They then tested the accuracy of the slide, and found that the accuracy was fairly consistent. However, because they couldn't achieve the distance portion of the myth, they were forced to bust the myth. Just to make absolutely sure, the MythBusters contacted the people responsible for making the video, and they confirmed that the video was made using computer graphics. ----- Left Hand Turn Driving a route taking only right turns instead of left turns is more fuel efficient than driving normally, because the vehicle uses up more gas idling while waiting for traffic to clear on a left turn than taking three right turns. "Confirmed" For their first test, the Build Team drove a regular size car on a controlled course. On the first run, they drove the car around a block using a left hand turn, but had to wait for a turn signal. In the second run, they instead took three right turns to bypass the signal, but the route was longer. The results showed that the car managed to cover more distance in less time taking right turns compared to left turns while only consuming less than one percent more fuel. For a real world result, the Build Team obtained a full size delivery truck, with the objective of delivering packages to several locations scattered throughout San Francisco. For their second run, they drove the exact same route, but replaced all of the left turns with right turns. Both runs included the treacherous Lombard Street hill. After reviewing their results, the Build Team discovered that the right turn route was more fuel efficient with a 3% difference, despite having to drive a longer distance. Kari then pointed out that this would be an ideal strategy for delivery trucks in urban environments, but would not work as well with regular cars. ------------------------------------------------------------------------- --
