Fiber Fill (those found in stuff toys)
Button cell battery (CR2032)
a couple of strong little magnets
To begin, measure the amount of fiber fill needed for your desired effect, here I just painted it yellow and black. There are several techniques out there on how to shape the fiber fill, some use hair spray. I think the paint I used was good enough to stiffen the material. I wanted to depict another small gundam (astray red frame) went through the huge psycho gundam. Shown here is the back portion of the huge gundam.
