Star Wars Color Changing Mug: Lightsaber Reveal Hot Coffee

Dark when empty, glowing when your coffee arrives

• Hot coffee ignites the blades

  The lightsaber print is dark when the mug is empty and shows vivid red, blue, green and purple when hot liquid fills it. Tea works too, so the reveal is not limited to coffee drinkers. If you are shopping for a color changing cup for the desk, this is the one where the color does the talking.

• Official-style Star Wars artwork

  The glossy black ceramic has a crisp white rim and a white C-handle that frame the print cleanly. The STAR WARS logo sits in the lineup with the lightsabers, so the mug reads as a fan piece on the desk and in the cupboard.

Three steps to your first reveal

1. 1
   Brew fresh

   Make a cup of coffee or tea with hot water, straight from the machine or kettle.

2. 2
   Pour and wait

   Fill the mug and give it a few seconds. The lightsaber colors come up as the ceramic warms.

3. 3
   Empty and repeat

   Once the mug cools, the print returns to its dark, subdued look, ready for the next refill.

The mug that hid its blades

The mug that felt like every other mug

The morning routine has a familiar rhythm. Coffee goes into a plain white mug, the mug goes back on the shelf, and nothing about it stands out. Gifts for a Star Wars fan tend to follow the same pattern, ending up as another shirt or keychain that gets forgotten.

The lightsabers were hiding in plain sight

Look closer and the print is a full lineup of Jedi and Sith, each blade labeled with its character name. Empty, the blades sit dark and quiet. Pour in hot coffee or tea and the colors rise through the ceramic, so the first sip comes with a reveal.
