Air bladder effect

An air bladder effect, or simply a bladder effect, is a special effect created for motion pictures. The effect employs plastic or latex balloons—known as "bladders"—which are concealed beneath the surface of foam latex or similar prosthetics. Attached to the bladders is a system of tubing that allows them to be inflated. When the bladders are inflated underneath the prosthetics (often skin prosthetics), it results in the prosthetics appearing to shift, bubble, swell, or pulsate. rdf:langString
