For Father's Day, let him know how you really feel: He's the best Dad in the galaxy!
 
On July 16, 2025, the students of Earth to Sky Calculus launched this 20 oz. stainless steel tumbler to the stratosphere onboard a cosmic ray research balloon. At the apex of the flight, it floated more than 102,315 feet above Earth's surface.
 
You can have it for $99.95. This Star Wars-themed cup keeps beverages cold for 12 hours or hot for 6 hours. It's safe, too, because the transparent lid seals tightly to prevent spills and is completely BPA-free. 
 
Bonus: It survived the stratosphere, and it will survive your kitchen, too. The tumbler is rated dishwasher safe.
