How to animate a projectile? (Fidget Spinner)

I'm making a custom weapon based off of magnorbs. ( https://i.imgur.com/cyvLPCy.gifv ) I can't figure out how to animate the projectiles themselves.I don't know how to manipulate the .frames, and would love some help. I also plan on giving away the spawncode if I can make this work with some help. Thanks in advance!
