Theres FOAM inside of my water bed mattress!!!???

when my water bed sprung a leak we drained it and carted it out to the back yard, and in the process of cutting it up to get it to the trash we discovered that there is FOAM inside!! real foamy FOAM foam!! it looks like the cotton batting thats inside quilts, or more like fibergl insulation only white. so am i the only one that didnt know that? oh, and i cant cut the dang thing, the scissors sort of bounced off, barely left a mark at all, and its too heavy to move. what should i do with it?
