Magical

I got two new unicorn mugs at Christmas to add to my ever growing collection of unicorn things. Both have the same magical quality, changing color when hot. This unicorn has only purple hair when cold or empty, but multicoloured hair when hot. Today was the first time I'd used it and discovered it's head becomes full of liquid too but that liquid doesn't tip out when drinking because physics. A design fault I'd say. Still, a lovely mug to join the collection.
