One other thing. This foam is really nothing more than a type of styrofoam, with smaller "bubbles" than the stuff you find in packaging material. That is, when it is made for packing and you break it up, little pieces or balls of it break off.
This stuff has finer "grain" than the packing stuff.
I'm not sure what sort of "flotation constant" this stuff would have....(hahah Flotation Constant... wonder if that can be worked out in physics somewhere. LOL!)
