Recoil Dynamics Test

A thick red rubber band was looped around the lower steel flange of the stairwell railing post. Inspection confirmed high polymer elasticity with zero dry rot. Blaster slung securely across my back plate, I gripped the band with both hands. Bracing my rigid boots against the rough aggregate concrete, I leaned backward four paces, stretching the synthetic band to maximum tensile resistance. I released my grip. The band snapped forward with a sharp, resonant thwack against the hollow post, sending a brief harmonic vibration through the steel. Kinetic snapback exceeded initial estimates. Recoil parameters fully verified.
