So what I need to do is cut two styrofoam spheres in half, one is smaller than the other.
The inside of one half of the larger sphere then will have to be hollowed out so that half of the smaller sphere will fit inside of it. I really don't have any way to do this with heat.
Any ideas how I could go about this? Maybe a fine metal cutting blade, like a hack saw, to cut them in half. But how to hog out the larger sphere?
My daughter has to make a 3D model of a bacteria cell that is shown as spherical with two layers.
Thanks in advance.
