This is one of the things that make you feel like you’re in a science fiction movie. In fact there is nothing magical or unbelievable but it makes a great effect. It is based on magnetic levitation of a magnet placed above another one. Power supply comes to the base platform. Once it is turned on, you can place the supplied globe in the air above the platform. It will hover almost an inch above the powered base and will rotate slowly. When you open the globe, you will discover a magnetic disc inside. You can put this disc above the platform and then balance stuff of your choice on it. There is a weight limit: you can use objects not heavier than 85 gr and levitation may not proceed properly if the object is made of iron or any magnetic material. Platform has eight LED lights which gives great light effect to the floating object.
For preventing incidents, be sure to keep the platform away from computers and other similar technology because it is possible to be damaged from the strong magnets. However the platform has comparatively small sizes: 18.5 cm long side and 3 cm height, thus making it easy to fit in some corner.Google+
