My son a friend of mine and i noticed a object that looked like a marshmallow it was moving from west to east when we first noticed it then it just stopped and hovered we watched it for about an hour it was about 60 degree and its a normal route for planes that are flying into the des moines airport and it seemed quite a bit higher than the planes on their descent i contacted my work which was about 6 blocks away to they north they said they couldnt see the one i was talking about but they seen an object that was almost directly over head and described an object similar to the one we were looking at at that time we went and got binoculars to get a closer look seeing it through them we noticed it was changing shape looked like it was vibrating and the outer edge was a light green color but wasnt staying green we stopped a guy riding by on a bike and pointed it out to him just to make sure we were not seeing things and he thought it was very odd later that night after my friend went home he called and said he looked around and counted aroud 10 objects like it but they had changed to a light pink in the morning the man who rode by on the bike said he spotted 2 more to the north last night and noticed 1 above his neighbors house around 6:30 am january 30 2018
