This weeks mug is from Northrop Corporation and was available after the introduction of the famous B-2, forever known as the "Stealth Bomber" due to its ability to not be seen on radar. Northrup introduced these mugs at their manufacturing facilities which showed a drawing of a radar on one side (with the silhouette of the B-2 visible) and on the other side some clouds, one of which is dark. (I note that the mug is old and the magic ink allows the plane to be visible, but when new, the cloud was completely dark.) Above the clouds is the name NORTHROP, and below is the caption B-2.
When hot liquid is added to the mug, the radar completely clears; the B-2 disappearing completely off the radar and on the opposite side, the plane becomes visible in the clouds. Color change is about average, but I do love the two sided effect.
