I was in a pool laying on a float looking up at the sky watching planes fly by when i noticed a flight of 5 orbs fly across the sky. they changed formation from disorganized to an organized triangle to a slash (all in line) then back to a triangle and abruptly change direction from approx. 60 degrees to approx. 150 degrees according to the compass on my phone. there was no noise emitted by them that i could hear. they were a white dull grey color. they were round. they crossed the entire sky in approx 20 sec. by the time i lost them over a low roof line and i stood up they had started off in the 150 degree direction and were gone i didn't see them again after i. tired to gain more ground to sight them they had either sped up or blinked up not sure which but they were not visible anymore.
