into the museum's supporting walls, meaning that "if enough people entered the museum, it would collapse". The exhibit was forcibly disassembled by the local fire department after a complaint that it was blocking a fire exit. In 2008, Burden reported having subsequently sold Samson to "a collector in Brazil". Later work Many of Chris Burden's later sculptures are intricate installations and structures consisting of many small parts. A Tale of Two Cities (1981) was inspired by the artist's fascination with war toys, bullets, model buildings, antique soldiers, and a fantasy about the twenty-fifth century – a time when he imagines the world will have returned to a system of feudal states. The room-filling miniature reconstruction of two such city-states, poised for war, incorporates 5,000 war toys from the United States, Japan, and Europe – on a , sand base surrounded by a "jungle" made of houseplants. The gallery-sized installation All the Submarines of the United States of America (1987) consists of 625 identical, small, handmade, painted-cardboard models that represent the entire United States submarine fleet dating from the late 1890s, when submarines entered the navy's arsenal, to the late 1980s. He suspended the cardboard models on monofilaments from the ceiling, placing them at various heights so that as a group they appear to be a school of fish swimming through the ocean of the gallery space. In 1992, he exhibited his Fist of Light during the Whitney Biennial exhibition in New York. It consisted of a sealed kitchen-sized metal box with hundreds of metal halide lamps burning inside. It required an industrial air conditioner to cool the room. Hell Gate (1998), is a scale model, in Erector and Meccano pieces and wood, of the dramatic steel-and-concrete railroad bridge that crosses the Hell Gate segment of the East River, between Queens and Wards Island. In 1999, Burden's sculpture When Robots Rule: The Two Minute Airplane Factory was shown at the Tate Gallery in London. It was a "factory-like assembly line which manufactures rubber-band-powered model aeroplanes from tissue paper, plastic and balsa wood". Each plane had a propeller powered by a rubber band, and when each was completed, at a rate of one every 2 minutes, the machine launched it to fly up and circle around the gallery. Unfortunately, the machine was non-functional for at least two months of the installation, leading World Sculpture News to question the intent of the piece
