Off-topic, but the title made me think of that scene from Cronenberg's Scanners [1], which has a pretty interesting backstory: The head itself was made using a number of different materials. First, a plaster head was used, but it looked more like an exploding statue. Then, they tried making a head out of wax, but it wasn't pliable enough and did not provide the desired effect. Eventually, the team settled on an internal skull structure formed with plaster, with outside skin and facial features rendered using gelatin. From there, the team packed the skull with just about whatever they could find. They used wax and latex scraps, along with various stringy bits and anything they had lying around the studio that they thought would fly through the air a little better. They even used bits of leftover burgers from lunch that day. From there, the plan was to blow the head up with explosives. The problem, the team found, was that any kind of explosive they used revealed sparks to the camera, which they didn't want. To portray a real sense of internal mental pressure resulting in the head exploding outward, they needed a different method. As the shoot wore on and nothing seemed to be working, special effects supervisor Gary Zeller told everyone to keep their cameras rolling, to get into their cars, and roll the windows up. He then lay down underneath the head with a shotgun, pointed it up beneath the back of it, and fired. The result is the exploding head scene in Scanners. https://screenrant.com/david-cronenberg-scanners-movie-exploding-head-effect-explained/ https://screenrant.com/david-cronenberg-scanners-movie-explo... 1.
