| "caption": "In a sandy outdoor setting, a bright orange toy excavator with a movable arm scoops sand and deposits it into a yellow dump trailer labeled \"Double E Heavy Industry.\" The excavator's bucket lifts and tilts, transferring granular material with visible motion and slight scattering. The vehicles rest on uneven sand, their wheels sinking slightly, while the operator’s hand manipulates the excavator's arm, demonstrating controlled mechanical movement and interaction between solid objects and loose particulate matter.", | |
