The MOVA Rotating Blue Ocean Political 4.5-Inch Diameter Desk Globe is traditional in style with vibrant blue oceans. This political map depicts countries in bright colors for easy visibility; labels stand out in crisp black. Inspired by the earth it self this unique globe is among the world`s most advanced. It rotates silently without the need for batteries or power cords. Create a tasteful display in your home or office with the included 3-fingered acrylic base.The MOVA globe is powered only by natural light and the force of the earth`s magnetic field. It contains an inner globe that rotates within the fixed acrylic outer shell. The space between them is filled with a clear non-toxic fluid that provides buoyancy and prevents contact betwee n the two globes. The inner globe floating and turning in a virtually frictionless environment is akin to the earth itself. A highly efficient drive mechanism within the inner globe ensures rotation in virtually any ambient light. Solar cells harness that energy and a magnetic element reacts to the earth`s magnetic field in the manner of a common compass to provide torque.The optical properties of both the outer shell and fluid have been carefully chosen to magnify features on the inner globe. A s a result the outer globe appears to rotate despite resting on the stand in quiet defiance of commonly held ideas about the laws of friction. This globe measures 7.25 inches high with the display stand. Beautiful and arresting it will form a meditat ive point of focus for any room.See our Globe FAQs
