This is super cool! There is now a Sorting Hat mug that will tell you which Hogwarts house you belong in but only when your drink is warm! It's like magic!
Figuring out if you truly belong in Gryffindor, Slytherin, Hufflepuff, or Ravenclaw is a job only the Sorting Hat can do. Thankfully, Pottermore has the definitive quiz (proud Hufflepuff here) to get sorted, but in case you're looking for something a little more magical, this Harry Potter Sorting Hat Mug ($14) will reveal your true house in a very magical way. When the muggets warm, it transforms from a simple black mug to show your shield and house emblem. What an awesome way to start your day, even if you're not an auror or working at the Ministry of Magic.
