total eclipse stamps
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.

I saw a comment online about them not working, but they totally did for me. I didn't try to change them with just my body heat, though; I held them over a just-turned-off electric burner. My hands are always so cold they'd never warm a thing.

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

I got some "bioluminescent life" stamps instead and those are pretty cool.

And--in case you want the eclipse ones--you can still sometimes get things by going to the USPS online store--they always have more than your local post office does. That's how I got these (though they took forever getting here, so maybe they had to like scour the US to find a post office to send them to me from.)
