Raise a chalice to the world of witchcraft and wizardry with this beautifully designed Harry Potter Colour Change Water Glass. The themed glass features the iconic Hogwarts crest, including the symbols of each of the four school houses and the famous school motto. When a cold drink is added, the crest will come to life, with each of the four quadrants changing to their respective colours of scarlet, green, yellow and blue, all within the gold outline of the crest.
