The interrelation between the liquid motion in the vicinity of a zigzag rising bubble and the interfacial motion of it in rest water has been investigated experimentally. The interfacial motion and surrounding liquid motion were measured by illumination imaging technique and PIV measurement, respectively. We discussed the asymmetric vorticity field of surrounding liquid and bubble shape deformation. As a result, it was confirmed that the curvature of outside at the inversion point was larger than that of inside, the vorticity of outside at the inversion point was also larger than that of inside, and these two parameters periodically fluctuate and have close correlation.
