Oh, wait... which type of P-Factor did you mean?
That looks more like spiraling p-stream

Its easiest to explain at the actual airplane. Go out to the airplane with another person. Have them push the tail down and hold it down while you look at the propeller (while its stopped of course). Look at the right propeller blade, then look at the left propeller blade. It will be obvious which one takes a bigger bite of air.
Same principle applies when you have a high angle of attack. Tail goes down and you get p factor.

I got one of these to explain on my CFI checkride. It makes a great visual tool, and its easy to explain p factor using this.

Hehe!
If you're not by a plane, say in a ground school, you could use something like this held as if the airplane is in a nose high attitude to help visualize the difference in prop angle of attack and relative wind speed.

Take two sheets of paper, index cards, business cards, or whatever you have laying around and hold them at angles like a propeller blade. Hold them level, then tilt them up as they'd be in a nose up attitude. You can see the difference then as well.
