The Mythbuster team examines the story that a heated jawbreaker could turn into an explosive bomb. They also examine whether a PVC pipe can hold enough electrical charge to kill a person. Finally, they test the myth that a common playing card could be used as a deadly weapon. Scientific concepts discussed include differential heating, energy absorption, pressure differentials, bite force, static charge build up, static discharge, friction, conductivity, insulation, grounding, Van de Graaff generators, electric fields, negative charges, electrons, humidity, flight aerodynamics, and rotational spin. The episode is available on either of the following DVD sets. They are identical.
The Mythbusters examine whether a tongue piercing will attract lightning during a storm, see if a handmade medieval cannon could explode with deadly consequences, and test if there is any way to beat the breathalyzer test. Topics of interest include electrical conductivity, electrical fields, electrical engineering, experimental controls, manipulating experimental design variables, metal contraction, Newton’s Third Law of Motion, a discussion of the relationship between mass, force, and acceleration, Newton’s Second Law of Motion, alcohol metabolism, and public safety.
