The Constellation Mug looks pretty unremarkable when empty. A casual observer might not even recognize the little white flecks as stars. But pour yourself a hot cup of coffee or tea, and eleven constellations โ€“ including Orion, Hercules, and Perseus โ€“ spring into view. Do want.

Yeah, we know temperature-sensitive mugs aren't really anything new โ€“ but this was too cool to pass up. Who wouldn't enjoy starting their day with a little sup from the heavens?
