My 5-year-old and I saw a bright spiky object in sky, which dropped/disappeared quickly in a couple seconds.

My 5-year-old and I had a walk in the evening on 4/26/2022, there's still some light outside, and the sky was clear. At around 7:50 pm, suddenly we saw a bright object in the sky at the north direction, which quickly dropped in 2 - 3 seconds, with no sound. From where we saw, the object was about the size of an average woman's hand, and its original height was close to what we usually saw about a small airplane. We have after-dinner walks almost every day and there's a small airport nearby, so we've seen quite some airplanes. Besides, we like to look up at the sky and discuss what we see when we walk, but this object was different from anything we saw. When my son drew what he saw, he drew six dark-blue lines that crossed at the center with light blue emission between the lines, he was very sure it's a blue object, but I saw a yellow object with 5-6 symmetric sharp corners. Both my son and have regular vision (no color blind). So what we are certain it was a bright spiky object that showed different colors to different people. There's no aircrafts close to it when we saw it. When it dropped, my first reaction was: oh no, it must be a big crash and we should hear some loud sound, but we didn't hear anything. We checked several videos about parachute flares, and what we saw were not like that. It may not be something from ET, but we just want to know what that is. Thank you!
