The performer shows a square box with a window in front and a square insert which fits in the box. When the inner square is in the box, it can be seen through the window on the face of it. He starts by lifting both items onto the table which is raised off the ground (Provide your own side table) and then shows them empty both separately and together by lifting them off the table in turn, and looking right through the tube/box at the audience, putting an arm through and moving it around etc. When the tube is lifted out of the box, the empty interior of the box can be seen through the grille. When the box is lifted off the square tube, nothing can be seen hidden round the tube. Yet, when the tube is placed inside the box, he reaches in and produces all manner of items. This is a new style of square circle that has an ingenious new insert that can hold many different production items. Made from Acrylic and made to look flashy on any stage!
