A black ball passes over us in perth, Aus, waAround 8.00am, me and my friend arrived at the beach. We decide the spot we picked wasnt breaking that well, so we moved on to where it was thought to be better. We moved allong the sand dune as we watched the clouds roll by. Just as we watched, we saw a black ball aroung 1 km away from us. As it flew, it curved and flew against the wind. It gradually came closer and as it did, didnt didnt appear to be growing in size. When it was directly aboves up approximatly 50m high, i went to grab my mobile to take a picture. As soon as i took my phone out of my pocket, the black ball slowed dramatically, i put my fone back into my pocket as the thought of abduction passed my mind. when the phone slipped back into my pocket, the ball sped back up and flew out alond the horizon towards the city. The object was black and in a perfect ball sha. It appeared to be tennis ball sized from where we saw but actual size was probably a bowling ball, to a gymball's size.it fully resisted the wind and showed no signs of drag. it made absolutely no noise and didnt appear to have any windows or abstract objects, it was just a ball. after this event occured, a severe thunder and hail storm cam in for about 1 hour, then the storm ceased into a beutiful warm calm day. because we were walking across the dune as a shortcut, no one else appeared to have seen it.
