My science teacher set me this homework, please, I need your advice....'You are the sole survivor of an aeroplane crash in the Himalayas, it is freezing but there is bright sunlight. You desperately need to defrost a Mars bar to survive. You have: a polished piece of metal, a piece of string, a sheet of white paper, and a frozen Mars bar. How will you survive?!'

Define the reflective properties of two surfaces, one of which would appear bright to your eye, but which had a low albedo, and the other of which would appear dark to your eye, but which had a high albedo, both surfaces illuminated by the same solar flux density. Can you think of any such surfaces? If so, describe them, if not, describe what the difficulty is.
