This transformative mug offers a science lesson each time you enjoy a cup of coffee. Aptly called the Planet Mug, it features a portrait of our galaxy that, whenever filled with a hot liquid, illuminates facts about the planets. For example, did you know that Uranus spins “backward” as well as “on its side” at a 90-degree tilt? Or that ancient Mars once had a magnetic field? These are just of a couple of things you’ll learn as you sip alongside the solar system. The cup will make you appreciate our incredible universe and prep you for the science category at your local trivia night.
