Need Help Understanding how to Animate a Flying Screw

[guadalcanal]

I've been stuck on this for quite a while and tried everything I could think of. I'm what you might call artistically challenged, but I'm stubbornly trying to do my own sprite animations for a game I'm making. If anyone could point me in the right direction for a methodology I might use to make this sprite look like the propeller is spinning, I would be very grateful.

Thank you!

I tried but I think I messed it up. Made it scroll up and shrink toward top/bot.

Thanks a lot! It's not perfect, yes, but it's better than anything I managed to draw.
