and elmers glue (white glue)is a by product of making real cheese. but i don't think its a good idea to spread elmer's glue on a sandwich and eat it.

didn't you ever wonder why Borden's (and elsie the cow mate, elmer) got involved with glue making? cheese production uses the curds, and whey is mostly not used or needed. but reduce it.. and bingo.. glue!--but in other places, they looked at the crude left over and said, bingo--food!)
