Now you see it, now you don’t. Just like an actual total eclipse of the sun, which is supposed to happen August 21st, 2017. Even the United States Postal Service is gearing up for the rare solar eclipse craze. They just announced the Total Solar Eclipse Forever stamp.
Just press your finger on the stamp and your body heat turns its black circle into the moon. When it cools off, it goes back to black. The USPS says it’s the first time they’ve used thermochromic ink, which changes color with heat and light.
The back of the stamp pane shows a map of the eclipse path. A total solar eclipse will be visible from coast to coast late August. It’ll start in Oregon and cross the nation all the way to South Carolina. It’ll be the first total solar eclipse to sweep the entire country in 99 years, according to NASA.
A total solar eclipse occurs when the Moon completely blocks the sun; turning day into night. Just like touching the new stamp. You can get your hands on them June 20th, the day of the summer solstice. According to Mashable, the next eclipse with a path like this across the U.S. won’t happen until 2045.
