I was in line for a ride called the "zippr" at the utah state fair park. when i looked up at the ride, i noticed in the corner of my eye there was a slow moving yellow ball leaving a fire-like trail behind it. at first i thought it was a comet. my phone was out of battery at the time, so i told my older brother to take a video of it. he pulled his phone but he said he couldn't see it, so i moved forward in the line a bit and saw it had moved behind a pavillion, so he stood where i showed him you could see them and took the video. there, i saw it split up from one fireball thing into four smaller ones. other strangers also noticed. i knew it wasn't a comet, because comets don't turn as often or abruptly as the object did. they kept the same movement patterns as it did before it split up. one by one, they slowly faded out and vanished. it didn't affect ne fellings or thoughts, but it was very strange.
