Object travelled silently around 60(?) MPH.At arms length about fist size-Multi colored and "evaporated".

When I was about 9 yrs. old I was playing "combat" w/ my 2 younger brothers and a friend in our backyard.I looked up at the sky and beheld an elongated egg shaped craft that had 3 dayglo colors that blended into each other.It was pink,orange & light green with tint red lights on the bottom of it. I banged on the kitchen window calling frantically,"Mom,Dad come to the window and look at outside!" Mom was first and called my Dad.They both looked out and saw it.It seemed to be surrounded by a "mist"-i.e. it wasn't clearly defined.It arced from the west and "evaporated" in the east over we believe Roosevelt race track.Our friend "Little Jimmy" ran home crying & screaming knocking over our garbage cans in the process.Honestly I don't remember the exact date.It was however Summer & it MIGHT have even been 1966.But to the best of my recollection it was 1965.Ellison Ave.seperated our backyard from Carle Place which we faced.This UFO was silent.
Date is approximate.  PD
