The answer to this admittedly lame riddle is, “No.” The reason is that the question at the very end asks if you can guess the riddle and there is nothing that satisfies the requirements above. Some say that pressure is the answer, but they can’t explain how it turns polar bears white or pancakes brown. Nothing turns polar bears white, any more than something turns a white person white, and heat makes pancakes brown, not pressure.
