Particles Rotate Weirdly

Hello everyone. I was recently working on Blender Guru’s “Create a Sizzling Title Intro” tutorial and the project uses particles. Everything rendered fine but a little fraction of a second after the particles hit the ground, they all align in one direction like iron filings being attracted by a magnet. If anyone knows why this occurs please respond. Thanks.

If I am not being clear enough please let me know.

the best thing to do would be to post a few screenshots of the problem

Here is the vid. PLEASE READ VIDEO DESCRIPTION. Respond here or on video comments.
