So... any options for doing this with a towel? :LOL:
I haven't got my copy of the Guide to hand, but this should be fairly obvious:
  1. Ensure approximately uniform anaerobic microbial growth throughout the towel (generally a given for hitchhiking towels)
  2. Moisten towel
  3. Drape over a rock of suitable size, covering all sides
  4. Wait a few days
  5. North is the side with highest bacterial population density (northern hemisphere only, obviously)
