Polarizing film blocks light when layered in parallel, and allows light to pass through when layered at a 90° angle. When sliced on the curve, it produces the illusion of a wavy surface. The phantom-waves vase uses polarizing film to create the visual illusion of three-dimensional boundaries within the vase. Branches and flowers placed in the vase appear to emerge through rippling water surfaces. Polarizing film creates rainbow patterns when it comes in contact with an adhesive. It also traps fine air bubbles between the film and the acrylic surface. To minimize these effects, we kept contact points to the bare minimum, and sandwiched the film between two layers of acrylic.
