Two budding Seattle scientists are making a name for themselves after sending a homemade spacecraft 78,000 feet above the Earth's surface on Saturday.
Sisters Rebecca and Kimberly Yeung are 10 and 8 years old.
In a video posted to YouTube by their father, Winston Yeung, the girls explain their experiment, which they called the Loki Lego Launcher - after their cat. A cutout photo of Loki hitched a ride on the craft, along with a LEGO figurine of R2-D2.

The girls used wood and broken arrow shafts to create the body of the launcher, which they also outfitted with styrofoam padding in case of a water landing. They attached two GoPro cameras to the vehicle to capture Loki and the Star Wars droid's travels.
A weather balloon filled with helium served as the duo's rocket fuel and a flight computer tracked the aircraft. After the journey, which took more than four hours, the girls used GPS to find the downed launcher 50 miles from their launch site.
