Even standing up close, Beijing-artist Li Hongbo’s sculpture of Michelangelo’s David looks like it is made out of marble or porcelain, but when it is gently pulled up, the bust stretches out beyond recognition, and when released, springs back to its original shape like a Slinky toy. The raw material that Li Hongbo uses for his sculptures is paper, thousands and thousands of sheets of paper. His average classical busts require gluing more than 5,000 sheets of paper together in a honeycomb pattern, using pressure to hold the sheets together. From there, he saws, cuts and shapes the huge block of glued paper to arrive at a rough sculpted form. Li Hongbo then shaves in the finer details and uses sandpaper to smooth the surface.
