science in a can I love this article. Late night visits to the kitchen to make toast generate that smell of hot metal as the element heats up, clicking occasionally. It never occurred to me that there might be a smell in space. But it makes sense. In October, when the air cools down, I can smell the cold. It brings a sense of foreboding: a need to take care of the draughts in my flat before they eat up my heating and cost me and the earth pounds of damage. This year I’m intending to make draught excluders for my doors and windows from old pillows and quilts.
