Ep 10. Crimes and Myth-demeanors 1

In the tenth episode of season four of Mythbusters, titled "Crimes and Myth-demeanors 1," hosts Adam Savage and Jamie Hyneman take on myths related to crime and investigation. They begin by examining the claim that a thief can evade detection by covering their body in duct tape and thus leaving no fingerprints at the scene of a crime. To test the myth, Adam and Jamie construct a full body duct tape suit and use it to attempt a break-in at a mock crime scene. They also try to fool a fingerprint scanner by applying various substances to their fingertips.

Next, the hosts investigate the idea that a car can be outrun by a person on foot if the runner zigzags rather than running in a straight line. They set up a race between a car driven by Grant Imahara and a sprinter while filming the events with high-speed cameras to analyze the patterns of movement. The results are unexpected and reveal surprising insights into the physics of running and driving.

In another myth, Adam and Jamie investigate the possibility of using a balloon to fool a breathalyzer into underestimating the amount of alcohol in someone's system. They construct a device using a balloon and a bottle of alcohol and test it against a breathalyzer machine. The results are inconclusive, prompting the hosts to try several different methods of making the balloon and placing it over the breathalyzer nozzle.

Finally, Adam and Jamie examine a scene from the movie Lethal Weapon 2 in which a car is flipped over by a forklift. They attempt to replicate the stunt by tipping a car onto its roof with a hydraulic lifting system and then using a forklift to try to flip it back over. The testing process includes several failed attempts and setbacks, but the hosts are ultimately successful in recreating the scene, with some interesting surprises along the way.

Throughout the episode, the hosts explain the science behind each myth and provide interesting facts and trivia related to the topics at hand. They also show their typical humor and banter, making for an enjoyable and educational viewing experience.
