The National Poo Museum, at the Isle of Wight Zoo, is the first in the UK to focus on crap featuring poo from humans and animals. Different types of faeces are displayed behind retro toilet lids. 

The oldest poo on display dates back 140million years.

Nigel George, one of the exhibition’s curators, said: “Poo provokes strong reactions.” We’re not going to argue with him over that point.
