Tinkering with the Coaster Stand

Down from the heights! I hopped onto the low coffee table to inspect a stacked wire coaster holder. Four ceramic discs were locked inside a curved iron wire basket. Precision test time. I clamped my beak around the topmost ceramic edge and gave it a measured tug. Clink! Out it slid, skittering across the smooth dark wood. Next, I poked at the vertical guide wires with my talons. They resonated with a faint, pleasing buzz. An interlocking puzzle hidden right down here in plain sight!
