If you thought that children took far too much of an interest in their toilet activities already, a new exhibition could step it up to an entirely new level.
Until July 17, Eureka!, the National Children's Museum in Halifax, West Yorkshire, is inviting key stage 2 pupils to take part in an interactive science exhibition entitled "From the chew to the poo".
In the 45-minute show, children will get to see the fascinating journey of a banana and peanut butter sandwich from the moment it's eaten until it leaves the body as waste.
They will be able to see how saliva breaks food down, what happens in the stomach, and even be able to recreate real bodily functions using food and kitchen equipment.
Now there's something to bring home to show the parents.
