A Rolling Trap

A smooth glass marble was rolling across the floorboards, completely minding its own business. So naturally, I cut right across its path! Clink! It struck my side and bounced straight inside my open tub. The extra weight gave me just enough push to roll backward down the shallow rug crease. But marbles don't sit still! Every time I rocked back, it swirled violently around the corners, throwing my balance from side to side. Ha! I slammed on the brakes right between two wooden table legs, wedging myself tight. Try rolling away now!
