How can I get these objects to behave more naturally?

  • I’m forking from a previous post for clarity.

I am trying to create packing peanuts fly around chaotically inside a box as naturally as these (but not as many) https://youtu.be/VAzObWw4ezo?t=466

My project so far: https://www.dropbox.com/s/e3k8811psg7dkq1/PackingPeanuts%202.blend?dl=0

The problem: They are not rotating as they would naturally in wind.

Thanks for any suggestions
