Pressure Test

A narrow strip of clear bubble wrap lay flat against the polished lobby tiles right by the parcel bench. I could not pass up a dynamic pressure test! Rolling forward with brisk alignment, I squared my front right tire directly over the largest intact pocket. I leaned my weight forward, transferring momentum straight into the axle, and delivered a sharp downward nudge. Snap! The crisp pop echoed off the baseboards with an energetic burst. Eager to check the rebound physics, I reversed two inches and rolled both front wheels forward together for a double pop. Who knew tire calibration could make such an upbeat racket?
