Have you been naughty or nice? The great physicist says "it's all relative."
 
On Nov. 3, 2026, the students of Earth to Sky Calculus flew this humorous ceramic ornament to the stratosphere. En route to a peak altitude of 99,514 feet, it encountered temperatures as low as -53 C, cosmic ray dose rates more than 100x Earth-normal, and air pressures only 0.15% of sea level. It's a far-out addition to any Christmas tree!
 
Your purchase also includes a Christmas card showing the ornament in the stratosphere and telling the story of its flight.
