As is known, water is traditionally the most frequently used fire extinguisher. However, it has its own particular deficiency. Based on the study and analysis of the fire extinguishing properties of water, the author has done a series of contrast experiments with water and its counterpart-gel extinguisher, which is able to improve the extinguishing behaviors of water by increasing the security of water in fire stamping. It can also helps to enhance the fire-extinguishing efficiency by adding some fire-resisting additives. The scale of wood stack used as fire resource in the author's experiments, the flux of gel and water are theoretically devised in accordance with the principle of energy conservation. The experimental device used for confecting gel extinguisher in a properly blending proportion of water and additives has been designed and manufactured by the author himself. The contrasting properties of gel extinguisher and water are compared, analyzed and carefully studied, including testing the mobility, resisting combustibility and fire-extinguishing features by using the author's own made experimental extinguishing device. The results of his experiments show that gel extinguisher enjoys better mobility in a certain concentration scope and doesn't increase the mobile resistance of gel inside the pipe. In the experimental concentration scope, the flowing resistance coefficient of gel extinguisher proves less than that of water as a result of the water's cooling area extension, which is critical for fire fighting. Since the cooling time of water is prolonged, gel extinguisher has obviously improved the burning resistance in comparison with water, which can effectively restrain the temperature rising of the burning objects and slower the spreading velocity of fire. Thus, it can be concluded that the fire-extinguishing effect of gel extinguisher is
