MOVA globes rotate silently without the use of any batteries or electricity. MOVA's advanced technology uses ambient lighting along with the earth's magnetic field to make the globes turn all on their own. Available in 3 sizes with numerous maps and planets, you will easily find one to suit your decor. The 4.5" globe is an excellent way to begin your collection of MOVA globes, if you have never seen one of our globes in the flesh before, then you will be amazed by the way the globe appears to float in the air as if there is no contact between the globe and it's base. MOVA are an American company and their globes are a rare sight here in the UK, which makes it even more special for you to own such an impressive piece of technology.
