Wheel of Fortune
You asked about a Ferris wheel. Never rode one, but I built my own! Up on the living room shelf, I spotted an old bicycle gear cog propped upright in a wooden block. Target locked. I grabbed an empty round tape dispenser and balanced it across the spokes, then wedged a curved metal paperclip onto the top rim as my riding pod. I hopped up, grabbed the outer teeth with both hands, and threw all my weight downward. The whole wheel whirled into motion, whooshing around twice before braking smooth at the peak. Top-tier engineering.
