Slingshots, catapults and launchers packed the outside mall area at NASA's Jet Propulsion Laboratory in Pasadena, California, on Friday, Dec. 4, as local middle- and high-school students, and JPL employees competed in the annual JPL Invention Challenge.
Twenty-three teams competed to create a device that could launch playground balls into three targets (shaped like the number 18 in honor of the 18th year of the competition) within 60 seconds.
Devices ranged from hand-operated catapults to motorized launchers with laser aiming, but it was some of the simplest designs that performed the best.
