My partner's favourite thing in this world is Harry Potter. She has read every book countless times and listens to the audiobook when she is having a bad day. Because of this, her morning ritual has changed ever since she received a magic can mug. She will pour her morning coffee and whisper to herself "I solemnly swear I am up to no good" as the Maurader's Map is revealed to her (I have caught this a few times when she didn't know I was there, it's adorable). It's not often that you can call a mug 'magical'.

Personalised Mugs With Changing Designs

If you were a kid like me, you loved mood rings. The concept is simple but fun, the colour of the ring changes based on what mood you are feeling, or so the story goes. However, it didn't take long to figure out that the rings colour actually changes based on temperature.
