      Scratch yourself — well done, you’ve just made some dust!

      It’s dead skin from our bodies – nice eh!

      It comes from lots of other things too! The soil, pollution, pollen (and even the faeces of the dust mites that feast on the dust!) – it’s basically just a term for any particles hanging around in the air or settled on surfaces.

      It is formed as part of a natural process that occurs when people forget to use a duster. Plus what the other scientists said!
