A explosive device is disclosed for collapsing an expansion-fit metal tube from within a hole of a metal plate of a boiler or the like. Modular displays may include a plurality of tiles having glass panels which are abutted together to present a composite display. Thus the thin plate 1, such as a semiconductor wafer or a metal foil, can be accurately, surely and efficiently pasted to the carrying member 2, and the thin plate 1 pasted to the carrying member 2 can be readily separated from the carrying member 2. The documents and shipping labels may be customer specific. The system can be used, for example, to display a three dimensional image of a patient’s body in a first state, to receive age and disease assumptions, and to display a three dimensional image corresponding to the received age and disease assumptions, thereby simulating the impact of lifestyle choices by representing the patient’s body as it would appear at various ages having various diseases.
