    This is great stuff… a wonderful classroom experiment. Okay, now how do I make magnetic putty?

      Probably just add iron filings (the black dust variety) to Silly Putty.

    Better check out the reviews over at Edmund Scientific.
    Looks like the same snake oil they were trying to pawn only they call it “Black Magnetic Thinking Putty”.
