Hello  Chris

Great show...

How does your body know the difference (usually!) between a fart and a poo?

Charlie Lupton

What do you think?

As others have "a-loo-ded" to on Twitter, the system is good, but it isn't flawless; this can give rise to the phenomenon of the "shart" - a fart with some faecal content - also know as squirts.

Touch cloth, turtle head, and of course the dreaded day after a curry!

OK, so from time to time it doesn't work, but most of the time it does seem able to tell gases from solids.

How?

People who have had a surgical haemorrhoidectomy sometimes say that this procedure appears to impact upon the nerve that tells liquid from gas and can result in some accidents, at least initially.

The real problem is the dreaded 'follow through'.


Oh dear! My fart seems to have lumps in it!

Who's that bird on TV who likes to look at peoples poo ?...she'd be up for some empirical experimentation. Just get a bunch of bums sat on a raised plinth with appropriate seating cavities and feed the owners a variety of fart and poo generating nutritional biomatter and let the fun begin !

Sounds like a Roman toilet. Didn't seem to bother them one bit either.
