Jamie and Adam attempt to isolate the key ingredients to get to the bottom of the Mentos mystery. Kari, Tory, and Grant test the myth that placing a postage stamp on a helicopter blade will cause a massive imbalance in the rotors. Some of the scientific concepts include nucleation, carbonation, chemical reactions, pressure, variable isolation, the cascade effect, surface area, surface pitting, thrust vectoring, center of gravity, center of mass, blade deflection, lateral motion, gas density, air and gas ignition ratios, and combustion ratios.
The Mythbusters test the ancient myth that the Chinese put a man into space in the 15th century. Jamie and Adam also attempt to verify if there is anything as free energy. Grant, Kari, and Tory investigate whether a spinning ceiling fan can act as a decapitation machine. Science topics include the Law of Conservation of Energy, structural integrity, Newton’s Third Law of Motion, equal and opposite reactions, thrust, forces, flight stability, thrust vectoring, exhaust gas pressure, perpetual motion machines, phase changes, density, internal and external energy sources, center of mass, animal and human analogs, and rotational inertia. The episode can be found on either of the following DVD sets (they are identical).
