This device is to huge and powerful, it's really hard to believe. I've had smaller units before that will float items weighing about 1 pound. This unit can float objects weighing near 20 pounds. Even though it's beautiful to walk in the room and see this unit sitting there, I love to try and hide the unit with various objects. The magnetic disc is hidden under the chessboard, for instance. For the floating books, I made a fake book and hid the magnet in it. The pillow is one of my favorites. The visual of a floating pillow supporting a 7 pound brick is fun to see. And then the last was just so cool to see. As a kid I dreamed of the Millennium Falcon. So to see it floating just brings it to another level of reality.
