Experience your own total solar eclipse at your desk or in your own home with this ThinkGeek-exclusive Solar Eclipse Heat Change Mug! When the mug is cold, enjoy the view of the Sun's corona in black and white on one side and in color on the other. Then, pour in your favorite hot beverage and slowly reveal the full Moon and the turbulent Sun! Behold! You could say the difference is like night and day. The background of the mug is black, helping the dramatic astronomical event stand out.
