Studies of the onset of instabilities were conducted on single hole and multi-hole contractions using laser speckle visualization. A well characterized elastic fluid was used with constant viscosity of 13.1 Pa-s and elasticity characterized by a longest relaxation time constant of 2.233 s. The onset
