Muggles just want to have fun
The final Harry Potter movie wrapped up the boy wizard's adventures on July 15, and with the possibility of an eighth volume in the series very slim, muggles — or non-magical people — may be looking for a way to continue experiencing the magic of J.K. Rowling's fictional world. (Well, until October 1 when Pottermore is open to the public.)
Luckily, there are a variety of ways you can interact with fellow wannabe witches and wizards and get a taste of life at Hogwarts. If you've ever wanted to catch a snitch, sample a butterbeer, take a course in Transfiguration or even fight the Dark Arts, you can. You won't even need a wand — just a little imagination.
