I don't know where else to put this so here's the story...

From Illinois abt 9:00 P.M. this happened

>I forget my headphones in my car
>walk out to my car to get them
>b4 getting to car look at the sky
>see 2 airplanes get close af
>I was wtf???
>then just as it looks like they are abt to hit the get close and drop this little sparkling ball, like a disco ball
> I'm like wtf wtf wtf?
>keep watching, it looks like it's attached to a parachute
>at this point both airplanes head off in different directions
>keep watching this orb fall
>then suddenly the thing bursts open and a bunch spark-like colors fly in a kind of buckshot manner
>seriously so curious and confused
>things rain down on the city
>it's not extremely bright, but definitely noticeable
>pls explain

basically I'm confused is this some government chemical shit or something else?
