But a group of researchers from Caltech university and NASA’s Jet Propulsion Laboratory have come up with an elegant and oh-so-fun solution: fire the damn thing out of a cannon. airborne and ready in less than a second The engineers’ creation is called SQUID, short for Streamlined Quick Unfolding Investigation Drone, and it looks rather like one of those whistling Nerf balls.
