''GERM'' experiment....

I don't know what this was exactly in aid of - but today I had to do an experiment which involved my hands being put under an ultra violet light to check for germs. Sure enough, it really put me off when I saw under the light what germs looked like under the microscope. I felt like looking away - I've washed my hands about 30 times today, including with a hand sanatiser and without soap - thing is I need them nails cut!
