Looking for something to do with the kids in the holidays? Drag them along to the Walter Rothschild Zoological Museum in Tring, Hertfordshire, where they can find out everything they ever wanted to know about poo (or big jobs, number twos, oomphs etc).
The exhibition, Poo: A natural history of the unmentionable, coincides with publication of a children's book of the same name. It will explain what faeces are made up of - not just the remains of food but worn-out blood cells, germs and other unwanted bits, such as worms that try to live inside the gut.
Using interactive exhibits and specimens, visitors can find out how, among other things, fossilised faeces (coprolite) can be used to discover the diet of extinct species such as Tyrannosaurus Rex.
The exhibition is free and runs from 3 August to 28 November.
