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. * Black oceans * 3-prong, clear acrylic base; acrylic shell * Uses solar cells and magnetic field to rotate * Requires no cords or batteries * Displays land masses as seen from space * 4.5 diam. inches; 7.25H inches
