Big Wheel Keep On Turning...
STEAMPUNK MONOWHEEL WOODEN GEAR MODEL
And this one will, running on rubber-band power after you spend a few happy hours putting it together. This all-wood, steampunky monowheel comprises (300) parts, and measures approx. 7-1/4" x 3-3/4" x 6-1/4" when completed. You'll see all the moving gears that run it in (2) modes: straight ahead with a turn-around finish; or continuous turning until it hits an obstacle, which means you can use it as a retro-futuristic bowling ball. Includes (19) spare parts.
