Just got a laser pointer w/ 5 modes (arrow, dot, line, etc..).
Anyway, when I shine it up at my ceiling fan, something weird happens. Obviously, every time a blade passes directly over head the image blinks on the blade, then quickly goes back to only being on the ceiling.
But here's the weird part. I'm almost certain that - even though the blades are passing over - the pointer always stays on the ceiling behind the blade (apparently, even when it's on the blade as well [I see two things then]).
You'd think that the cycle would just be simply reversed (the blade lights up and the ceiling's off; the ceiling lights up and the blades off), but as best I can tell, that's not what's happening. If it is happening, it is definitely not as defined as the blade blinking. I've gotten on my bed so I can see the ceiling without looking through the fan and I've come to the same conclusion.
But this doesn't make sense. What's up?
(PS - I've also tried switching angles etc. And since the pointer can project larger images like arrows, it's easier for me to test than if it were only dots.)
