Observations of the motion of a rising bubble in a wormlike micellar system are presented, obtained in both a rotating toroidal cell and a stationary box. For equimolar concentrations of aqueous CTAB/NaSal (8-11 mM), bubbles larger than a certain volume undergo oscillations in shape which include an apparent cusp. The average frequency of these oscillations is found to increase with bubble volume.
