This product made us laugh when we first saw it! At plain sight it is a standard black mug as they come a dime a dozen and in big white letters it say OFF. Nothing fancy, but once you add the hot beverage of your choice, the mug changes color and is turning white and in big black letters it states: ON.
Here's one to help get you going in the morning. The On-Off Mug is coated with a heat sensitive pigment that turns the mug from black to white as it gets hot. Without any liquid in it, the mug looks black and says "OFF" on it. Pour in your morning beverage and it'll gradually turn white and read "ON." Maybe marveling over this simple color changing pleasure will help you wake up.
