The blanket is an insulator. Its job is to prevent the transfer of heat from one side

of it through to the other side.

-- Ice is cold. If you wrap a block of ice in a blanket, the ice will stay cold and

melt very slowly, because the heat of the air can't get through the blanket.

-- If you are alive, your body is warm. If you wrap yourself in a blanket, you will

stay warm, because your heat can't escape through the blanket.
