Though GPS or Google Earth will prove handier in case you want to spot the desired destination, but you’d put all your gadgets aside in front of this Perpetual Motion Rotating Globe that rotates just like the Earth endlessly sans batteries, touch and power cords.



The globe apparently violates the laws of thermodynamics as it’s impossible to attain perpetual motion owing to friction. But exceptions are always there and this globe is able to do it with the help of earth’s magnetic field. ‘A photoreceptor inside the globe gathers room light to power an internal drive that spins the globe by means of a force from the earth’s magnetic field.’



To counter friction, the globe is packed inside a acrylic shell filled with a clear liquid. Even if you’ll hold it in your hand it’ll continue its motion.
