The characteristics of bubble rise phenomenon in three liquids were studied in a newly designed rig and are reported here. The experimental rig consists of two transparent cylindrical columns - one a polycarbonate tube of 125 mm diameter and the other an acrylic tube of 400 mm diameter. The rig also consists of a lifting device designed to hold a video camera for taking bubble images. Water and two non-Newtonian fluids (0.025% and 0.045% by weight of polyacrylamide solutions) were used in this study.
