The German industrial conglomerate Festo created a remote-controlled flying device modeled on the Manta Ray. The Air-Ray basically a helium-filled ballonet in the shape of a manta, but what separates this from a typical party balloon is that propulsion is achieved by a beating wing. It literally “swims” in a sea of air. Take a look at how graceful it moves in the video below.

Sponsored by rival churches, the object of this is to hit the other church’s bell. The tradition started in the 1800’s during the Ottoman occupation when the Greeks had their cannons confiscated. They responded by launching their own homemade rockets against the Ottoman Turks.
