The Mova Rotating Mars 4.5 in. diam. Globe is a perfect conversation starter. Get a closer look at Mar, named after the Roman god of war. Mars is also called the ''Red Planet,'' due to the iron oxide on its surface. Most notable is how this little planet seems to float effortlessly on its clear acrylic base. This rotund orb operates on low-light solar cell technology, so no batteries or power cords are required. Simply expose the globe to natural or artificial light, and enjoy the rotating art. About Mova Globes: By using a unique design, highly efficient solar cells, and the Earth's magnetic field, Mova has created a stunning line of globes that appear to rotate even though firmly rooted in place. This effect is created by placing a smaller globe inside the outer acrylic shell and filling the space between with a clear fluid. The inner globe floats in the center, while the solar cells and magnetic drive cause it to rotate. The graphic features of the inner globe are magnified by the acrylic shell and fluid, making them appear to be on the outer shell; this causes the illusion of movement of the entire globe. Ultra-efficient solar cells mean that your globe will rotate even in low light, using the energy from your room's lighting. This automatic movement, coupled with stunning graphics, makes the Mova globe a perfect choice for any home or office. Features an elegant, clear acrylic stand. Developed from high resolution satellite imagery. Powered by solar energy and Earth's magnetic field. Requires no batteries or wires to function. Measures 4.5 diam. inches.
