So, somebody has managed to extract H2O, along with some minerals, out of excrements and you call the extract "poo" ? Do you study chemistry at all in the UK?
This comments section is full of teenagers, where are the UNIX system admins, Microsoft certified surface specialists ?
Could you use a joke icon next time ? Coz, guess what, we all drink poo, all the time [if all it takes for the H2O molecule-minerals combo to be called poo is they must have been in feces at some point in time]
