Valentine's Day is coming. To get ready for the most romantic day of the year, the students of Earth to Sky Calculus launched these love birds  to the stratosphere on Jan. 1, 2021. Floating on a cosmic ray balloon, they flew to an altitude 102,690 feet above the Sierra Nevada mountains of central California.


The birds are made of high-quality Borosilicate Crown Crystal often used in lenses and prisms. That's why they glitter so colorfully in sunlight at the edge of space. After the balloon exploded (as planned) the payload parachuted back to Earth, landing on the west side of the rugged Inyo Mountain. The love birds had a wild ride, and the students got great data for their cosmic ray monitoring program.


Each item comes with a greeting card showing the birds in flight and telling the story of their journey to the stratosphere and back again. They make great Valentine's, Mother's Day, and romantic birthday gifts.
