The formation process of a vortex ring by an exploding wire in water is investigated exper-imentally. The formation of a vortex ring has been assumed to be related to the water flowinduced by an exploding wire (S. Watanabe et al.o J. Phys. Soc. Jpn. 64 (1995) 3748). Thisassumption is examined experimentally. As soon as a wire explodes in a pipe with one outlet, avapor bubble starts to grow around the electrodes and then performs a damped oscillation. Theradius of a bubble is observed to reach its first maximum at 3.5 x 5.0ms after the explosion.The formation of a vortex ring at the outlet of a pipe is confirmed to begin at 0.35 ms after theexplosion and to end at 2.0 ms. These two observations lead us to conclude that the formationof a vortex ring origirnates from a high speed flow of water generated by an expanding vaporbubble of an exploding wire.
