CPO Quick Tip : Propeller and Motor Direction and Pusher vs Standard Props

CPO Not-So-Quick Tip .
I'm not sure you can call a 10 minute video a "Quick Tip" but it's really a collection of several tips with regard to the proper orientation of the propeller (both pusher and tractor) and proper motor direction. I toss in a few other tidbits, like the difference between a standard prop and a pusher prop (since I conveniently have an example of both) and show the difference between the stock Hobby King Bixler 2 prop and the APC version. I decided to also dazzle you with an unconventional demonstration of identifying correct prop and motor direction with the use of an M&M. ;-)
My thought is that perhaps one or more of these tidbits will help the concepts click with newbies. Being new myself, I had to do a bit of research and thought exercising to sort this out. Hopefully this will consolidate some of that effort.
You'll note that this is slanted towards the Bixler 2 build I am working on, but I am hoping that the concepts are universal in application. I don't have every type of prop (nor have I seen them all) so if this method doesn't align with your equipment, feel free to disregard it.
I am sure there are other tips or methods to solve this problem, but I think I was able to cover some key ones that I have run across in my build research.
I hope this helps someone.
