  ‘Was there anything else on the dinner menu?’

  ‘Vole-au-vents and Cream of Rat,’ said Gimlet. ‘All hygienically prepared.’

  ‘How do you mean, “hygienically prepared”?’ said Carrot.

  ‘The chef is under strict orders to wash his hands afterwards.’

  The assembled dwarfs nodded. This was certainly pretty hygienic. You didn’t want people going around with ratty hands.

  I have bad news, most (?) paper towels, toilet paper, and even the toilet seat covers are microscopically transparent, meaning there are plenty of gaps for microbes to get through.

    Paper towels folded over on themselves absolutely create a barrier between my hand and the door handle. I’m not talking about flushable paper or toilet seat covers

      Paper towels are able to absorb water because of cellulose’s natural gaps and spaces:

      Most bacteria are about 1 micron, and these gaps range from around 1-10 microns.

      Especially if damp, it can be argued that they don’t stop the transfer of bacteria. It’s possible that your bacteria transfers through it and vice versa. This is all before the fact that paper towels can already harbor bacteria on their own.

      That being said, paper towels do block some. You just shouldn’t think of them as sterile or a magic blocker for bacteria.

        I’d be interested to culture petri dishes off my hand after I use a new paper towel to turn off the faucet vs grabbing the wet handle with my entire hand and shutting it off and then drying off my hand…
