Wonder what work experience kid they got to volunteer to test this thing out when they were designing it???
"Look Johnny, we have this machine and we're not sure if it'll work. All you gotta do is....."
"We're pretty sure it'll work!"
Apart from the mortal fear most blokes would have about sticking anything near that contraption, the sanitary aspect if it would be more than a little worrying too....
Maybe they should have an Iodophor spray attached to it
