During a break at work, i noticed an object hovering above a nearby tree. after approximately 15-20 seconds of observation, i pulled out my phone and started recording. i knew that what i was seeing was unidentifiable to me. the object looked very fuzzy at times and nearly transparent, other times it looked like a large white bag that was filled about 75% and slowly tumbling in the air. the object appeared to pulse light on its surface or reflect flashes of sunlight. the top of the tree in the video is about 125-150 feet from my position.
