The one I've seen is a Mardi Gras mask. Cut a paper plate in half. Glue (or staple) a craft stick to the lower corner of the flat side. Cut a slot to look through. Cut a 3" (or so) Styrofoam ball in half, glue glitter or paint with glitter paint, glue to paper plate just above the slot, as two eyes. Hold mask in front of face. If desired, paint or glue other face features on mask. Staple two craft pipe cleaners to the top of the mask as antenna.I have also heard that some people use a large Styrofoam ball as a base to make a papermache mask, which is then removed.See also, "How do you make a mask out of a sheet of Styrofoam?"

A model house/building your own world (Styrofoam ball) and anything you can imagine.
mass is sort of like the measure of an objects volume, and has no set number per substance, but density is a fixed figure. As to which object is denser, it depends what type of metal you are talking about, but most of the time metal would be more dense. As to how much mass they have, it depends how big the piece of Styrofoam is, and what type and how big the metal is.
No. It's not necessary.
