This is not a trick! The advertising product is not hanging from an invisible thread. It is actually suspended by an impressive electronically controlled magnetic system. The magnetic head above the product contains an electro magnet and a magnetic field sensor, and the frame base accommodates the micro-processor and the electronic control components.
So you can move your hand around the object and even push it around. A switch at the back of the unit allows for the product to automatically rotate in either direction. It's easy to insert and remove objects thanks to it's unique audio and visual indicators and a spacer (provided).
