The Aviator: Bi-Plane Coaster
Sometimes you want a coaster that is more. More gears, more to do, more fun. If that sounds like you, then you need this coaster. This coaster is made of wood with an acrylic top. When you turn the top all 8 internal gears move. Once you start turning it its hard to stop - the movement is mesmerizing. The 2 layers of gears create a kaleidoscope of movement!
This version is made from stained wood and is 4.5 inches in diameter by about 1 inch high.
