  1. I am surprised that my filthy watch strap ‘print’ didn’t grow into a ‘forest’, but the watch face produced an impressive circular growth. This was a great thing to do with the kids in the Summer holidays I can’t wait to show the children and others the results – fascinating – well done and thank you to Rachael, Nicole, Oxford University of Natural History and the John Radcliffe hospital.
