nice illusion.rnrnBut somewhat easy to see what happens...rnFirst of all he has put down the tape before the video. then he has the 3D cube placed on top of the tape, so you can't see the tape. When he takes the 3D cube closer to the camera, he slides it out of the picture, instead of placing it back on top of the tape.. the cube is created to leave one side standing up, to keep the illusion. rnrnThe disc is just switched to a ball just under the cam, before he places it next to the cube.rnrnClose up magic is the way to go. Not moving stuff behind the camera.!!!
