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.
First, the Mythbusters test the tale that a rocket propelled car can become airborne, then they examine the story that mixing Pop Rocks and soda can cause the stomach to explode. Science topics discussed include thrust and horsepower conversions, drag, aerodynamics, velocity, lift, forces and acceleration, free body diagrams, carbonation, gas pressure, organ elasticity, chemical reactions, chemical equations, and carbon dioxide formation.
