What a disappointment. Me and my husband at least thought this part of the day would be interesting. It's not a paper mill, just a room with some old paper making equipment in it. The only bit that's (sort of) in use is a big dip tank with paper fibres in it. The tour guide scoops out some fibres on a rectangular sieve and they're allowed to press on it (to squeeze the water out). Then everyone gets to look at the wet paper before they put it back in the dip tank again. Rubbish!
