On Nov. 18, 2019, the students of Earth to Sky Calculus launched a cosmic ray balloon to the stratosphere. This sterling silver sunflower pendant hitched a ride, 111,352 feet high. Inscribed on the back with "forever in my heart," each pendant comes with a greeting card showing the item in flight and telling the story of its journey to the edge of space. These make great Christmas gifts.
Bonus: The pendant contains a tiny chamber, which you may fill with the ashes of a loved one or anything else you wish to keep close to your heart.
