JK Rowling reveals how wizards actually poo!

There are plenty of unanswered questions that have been left in the wake of the eight classic Harry Potter movies, but one really stands out.

How do the students of Hogwarts poo?

Throughout the eight movies, not once did we ever see the students actually using the toilets or hinting at the fact that they were heading out to relieve themselves.

It turns out that Rolwing herself revealed the answer on Pottermore: 

"Hogwarts’ plumbing became more elaborate in the eighteenth century (this was a rare instance of wizards copying Muggles, because hitherto they simply relieved themselves wherever they stood, and vanished the evidence)"

So they never actually had to use a toilet, they would just simply 'magic' the remains away.

Now that's a camping skill that could come in handy...
