Can someone explain to me the effects the propellers are causing?
Looks rather neat.

Sure. The tips of the propellors are approaching the speak of sound, and as happens with jets when they do a high speed low pass or cut a high 'G' sharp turn, the air around them is first compressed, then released back to normal atmospheric pressure, causing the moisture in the air to be released as a fog.
