A number of small scaled explosions were carried out. The source of the explosion is an exploding wire, energized by rapid discharge from an electrical capacitor. The explosions are nuclear-like in that there are substantially no combustion products. In order to approximate a point-source explosion, the exploding wire consisted of No. 40 nichrome wire with lengths ranging from 2.3 mm to 4.5 mm. Burst points ranged from a depth of 63.5 mm beneath the water surface to an altitude of 100 mm. Bubble growth and progress of shock fronts in the air and in the water were followed through a schlieren optical system by means of very high speed photography. Pressure-time information, in the water only, was provided by piezoelectric gages. Surface waves were followed by means of high speed photography.
