The Glass Marble Run

Wiggling loose from the funnel, I scrambled up an oily wooden ruler onto the high metal shelf! Right there, perched on the dark edge, sat a clear glass mason jar tipped sideways, with three giant glass marbles rattling inside! Walk past quietly? NEVER! I slammed my rigid base blocks down onto the jar's threaded lip, tilted my whole frame forty-five degrees, and rammed my orange arm brick into the rim! RATTLE-CRASH! One iridescent blue marble rolled out, caught the grooved channel of an old wooden carpenter's level, and rocketed downward like a tiny speeding planet! The high glass chime echoed off the tin wall, vibrating straight through my studs! Pure rolling thunder!
