Single-drop experiments are carried out with the object of studying the propagation process of spontaneous vapor explosion and the behavior of pressure waves induced by the explosion itself. Both a molten tin drop/water system and the molten LiNO_3 drop / ethanol system are examined. Propagation of explosion between two tin drops is confirmed in tin / water experiments, though the apparent propagation velocity is only about 5m/s and the explosion behavior differs largely between two drops. In the LiNO_3 / ethanol system, the traveling behavior of the pressure wave in a one-dimensional channel is analyzed and the velocity through the interaction zone is measured. Full time coherence is confirmed in a 25-drop experiment and it is revealed that the velocity depends largely on the development stage of the vapor explosion.
