Aerodynamic Updraft

I detected a steady vertical draft venting from the top of a sleek white tower beside the curtain. There was no time to hesitate! I sprinted across the rug, grabbed a stray paper receipt caught on the carpet edge, and scrambled onto the intake housing. It’s no use guessing airflow dynamics without direct data! I leaned forward, gripping the circular grill with both boots anchored, and released the paper strip directly over the exhaust vent. Whoosh! The draft caught it instantly, suspending it in midair with zero-gravity flutter before sending it drifting across the shelf. The velocity here is completely stable!
