A new type of stamp has been developed for the United States postal service which comes to use from the month of June. The stamp is known as total solar eclipse forever stamp, which is the first of its kind stamp to be used in the United States postal service.
According to Phys.org, after just touching the stamp with the finger, there will be a magical transformation of the existing image of the stamp. The total solar eclipse forever stamp has currently an image of blacked out the sun, but when the image is touched with a finger, it will be changed into the moon. After the finger is removed, the eclipse will reappear.
The reason behind the magical image transformation of the total solar eclipse forever stamp is heated transformation. The ink used in the stamp image is temperature sensitive stamp and the entire trick is played by it. These types of inks are known as thermochromatic inks.
United States Postal Service reported that the total solar eclipse forever stamp will commemorate the August 21 solar eclipse. The August 21 solar eclipse will be the first total solar eclipse which will be visible in the United States since the year 1979 and the first ever solar eclipse coast to coast since the year 1918.
A map of the diagonal path of the solar eclipse happening on August 21 has been printed on the back of the total solar eclipse forever stamp. The image which is at the stamp is taken by astrophysicist Fred Espenak, also known as Mr. Eclipse of Portal, AZ. This is the image of a total solar eclipse which was seen from Jalu, Libya in the year 2006.
The designing of the total solar eclipse forever stamp has been done by the art director Antonio Alcala, of Alexandria. The stamp will be released in June, in the period of the summer solstice. The Total Eclipse of the Sun stamp is being issued as a Forever stamp, which is constantly equivalent in incentive to the present First-Class Mail 1-ounce cost. The Postal Service gets no tax dollars for working costs and depends on the offer of postage, items, and administrations to reserve its operations.
