The head box is suspended from overhead, and allows Elise to be restrained in a straitjacket and an ankle spreader bar. As Elise squirms and screams her breath fogs up the transparent plastic which makes it hard for us to see what's going on inside the box. This head box was inspired by the movie 'Saw' which featured a similar box which was slowly filled with water with the subject's head inside. You'll need to watch the video to see how the poor guy deals with this seemingly impossible situation.
