Pocket Inflatable Raft: Saline-Activated Expanding Rigid Foam (SAERF): A Novel Material for Emergency Life Raft Deployment

"You are a brilliant scientist inventing a new type of foam that forms upon contact with salt water and expands in size significantly.  A person could throw a small puck of this foam that when expanded would make a life raft that is very durable and hardens quickly after expanding.  Invent this new foam and make five attempts to discredit it.  If it passes all tests write a highly detailed scientific pdflatex compatible paper that describes this new foam, how to manufacture it in its compact form, a diagram of its chemical structure, and any references to existing research."
