The Constellation Mug | Heat Changing Star Mug

You don't have to be a rocket scientist to see why the Constellation Mug is one of the stars of our range. Practical and educational, this heat changing mug is the perfect gift for anyone who loves to huddle up with some hot chocolate or a steaming cup of coffee and spend the evening gazing at the stars.

Ideal for amateur astronomers, this marvellous Heat Changing Star Mug will magically change to show you the shapes of six famous constellations when you pour your drink into it. Ursa Major, Leo, Canis Major – you'll be able to learn about these and more, just by making a cup of tea, when you have the constellation mug to hand.

The constellation mug comes in a cool, rocket-shaped, presentation box too, so it's a stellar stocking filler option for anyone aspiring to be the next Tim Peake or Professor Brian Cox.
