On May 2nd, the students of Earth to Sky Calculus flew a payload of hammers to the edge of space, 35.0 km (115,000 feet) above Earth’s surface on board a high altitude helium balloon. After the balloon exploded, as planned, the tools parachuted back to Earth, landing in the foothills of the eastern Sierra Nevada mountains near of Bishop CA.


These compact 8 oz. hammers are light enough to fly on a balloon yet dense enough to deliver a powerful blow. The magnetic head holds a nail for one-handed starting, and the stubby 6 in. length is perfect for tight work areas.


For $97.95 you can have your own space hammer along with a unique gift card showing a hammer floating at the top of Earth’s atmosphere. The interior of the card tells the story of the flight and confirms that this gift has been to the edge of space and back again.
