Logical riddle, not to detect.

[Mega`Adnan]

This is perfectly synchronized speed propeller that seems to be it is not spinning
like in this video, you will see that the propeller moves slowly, actually moving very fast

+ for adnan

Yea, when the fan is spinning so fast, it show some kinda line effect that slows down slowly, and then it stops for the moment, and then it start accelerating reverse than fan's motion. I hope that's what Stroboscopic effect means.
Also, camera is not so fast to detect it (like 20 or 30 fps), so Helicopter is showing that it's wings are not moving.
I hope that's good answer. xD
Ty j0hny.

Here's another one. What's this riddle about?

The more you use, the more you have
And yet you always have the same number.
At least until the set from Belgium tears you asunder.

What's wrong with this picture? What item is wrong which course should not be there?

I was gonna say the lamp since cats have excellent night vision, but then I saw in the video there's a human living there too. So I dunno, I'm stumped.

I'm going with muscles, Bloopy. The Belgium bit had me puzzled, but then I thought of cities and thought of Muscles from Brussels

Nicely done, Dr One

A whole lot of nothing means a call to action.
It exists both inside and outside.
The faster you walk towards it, the smaller it becomes, but running away from it makes it shrink as well.

Nothing would be a vacuum, so things expand into it. The last line describes length contraction.
