[citation needed] Zapruder had planned to film the motorcade from his office window but opted for a better spot in Dealey Plaza where the motorcade would be passing. [16]
The creation of sparks from metals is based on the pyrophoricity of small metal particles, and pyrophoric alloys are made for this purpose. [2] Practical applications include the sparking mechanisms in lighters and various toys, using ferrocerium; starting fires without matches, using a firesteel; the flintlock mechanism in firearms; and spark testing ferrous metals.

Liquid oxygen has a clear cyan color and is strongly paramagnetic: it can be suspended between the poles of a powerful horseshoe magnet. [2] Liquid oxygen has a density of 1.141 kg/L (1.141 g/ml), slightly denser than liquid water, and is cryogenic with a freezing point of 54.36 K (−218.79 °C; −361.82 °F) and a boiling point of 90.19 K (−182.96 °C; −297.33 °F) at 1 bar (14.5 psi).
In the same ABC documentary, Myers uses a close-up examination of the Zapruder film to justify the single-bullet theory and calls attention to frames 223 and 224 on the Zapruder film, where the right-side lapel of Governor Connally's jacket appears to "pop out," as if being pushed from within by an unseen force.
