Children at the exhibition certainly seemed to be enjoying themselves too.
Ellie, 9, from London, added: "It's absolutely great, it's good fun. My favourite bit is where you have to smell the poo and you don't know what kind it is - it smells nasty. I thought it was a rat poo but I'm not sure yet."
And Cleo and Ged, from Herts, had great fun trying to identify the animal poo and peering at the faeces with a giant magnifying glass.
Who would've thought poo could be so much fun?
The exhibition is on at the Walter Rothschild Zoological Museum in Tring, Hertfordshire, until Sunday 28 November 2004.
The book, called Poo: A Natural History of the Unmentionable, by Nicola Davies and illustrated by Neal Layton is on sale.
