Transforming stamp released by Postal Service
LARAMIE, Wyo. (AP) — The U.S. Postal Service has officially unveiled a first-of-its kind stamp that transforms with the touch of a finger and is dedicated to this summer’s total solar eclipse.
The 49 cent stamp uses temperature-sensitive ink. When a person touches it, the body heat transforms the image of the blacked-out sun into the moon. Once the figure is removed, the eclipse reappears.
In addition, on the back of the sheet of stamps is a map of the eclipse’s diagonal path across the U.S. on Aug. 21, when the moon comes between the sun and Earth.
