total eclipse stamps

[asakiyume]

I thought these stamps were just cool because hey: cool image! Black and eclipse-y. I've received some on letters and I'd recently bought a sheet.



But then missroserose sent me a letter with this stamp and pointed out THAT IT CHANGES WHEN EXPOSED TO HEAT.

And I tested it, and it's TRUE. if you expose the stamp to heat, the silhouetted moon suddenly becomes pale and reveals all its features. SO COOL.

What a fun thing for the post office to do. Thank you, USPS.

Oh wow, what a neat idea! I almost never send letters, but I want a pack of those stamps anyway now just for the coolness factor.

(This is an ominous icon to use with an enthusiastic "yay science!" comment, but oh well; it's my most moon-related one!)

Ominous icons for the win, I say. Throwing the volcano icon up just for the heck of it ;-)
