2 cone shaped objects, at first where conjoined, then seperated and flew away. metalic at first then changed color as they where flying away.

i seen an odd shaped craft hovering in the sky, ran in my house and got my video camera, recorded it detatch and fly away... they where in a cone shape in front and in the back had some type of "compartment" on the back... no apparent propultion system, no wings, and no sound. they where about 120 to 170 feet in the air- i would estimate about 25 feet in length, 10 feet tall.also as they where flying away, they seemed to have a "glow" of assorted colors. have a videotape of this whole thing...
