Tetris mug! When you put a hot beverage into this Heat Changing Tetris Mug, the board changes. And it changes to the perfect scenario too- the long straight piece coming in to knock four lines off at once. Bonus! No you can’t actually play Tetris on the mug (without gluing your smartphone to the side- not recommended) but since it’s officially licensed, it looks just like the real deal and not some knock-off. This ceramic mug holds 12 ounces and features the same Tetris image on both side. Cool..err hot.
