As I understand it, the ability of the beads is predicated on Volume. The bead sheets are the same as the bead except that they are cut into sheets (made of material that escapes me me at the moment). For any given volume obviously yopu can define that in an infinite set of dimensions. My idea was to use the sheets sized to the particular volume of your coolidor and, depending how how fancy you got with the internals, you could create layers of beads by subdividng the sheets. It would also seems to me that since thay relatively thin that but greater in area, they would would real well for the tupperware approach
