Getting nice motion blur on propellors and rotors is infact quite difficult, particualrly with still photography in most digital cameras,.
Set the shutter speed too low (long exposure) and you'll get blur but you won't see it because of the over exposure white out, set the shutter speed higher and you'll get stopped or worse, "bent blades".
Most consumer level cameras just don't have enough of an arpeture setting (f-stop) to balance out the long exposure.
@amanda "they take them up and turn it off to test the helicopter if it were to happen for real and to test the back blades", your friend is very very confused.
All helicopter pilots are trained in the event of engine (or gearbox etc) failure to autorotate, that is, the rotors disconnect from the engine and "free-wheel", it is the free wheeling that creates sufficient lift to get you to the ground somewhat under control.
Autogyros (gyrocopters) in fact use this autorotation as the primary means of lift, an autogyro's rotor is not connected to the engine in flight at all, the engine uses a propellor to push the aircraft along and the rotors free-wheel to quite a speed and generate the lift to rise, and arrest descent.
If the rotors just STOPPED like the video in real life, you would have a large splat, preceeded by several seconds of terrified screaming and a whooshing sound as you plummet directly downwards uncontrollably to the earth at unsurvivable speeds.
Perhaps Kevin didn't realise that the lamp was in a pivoting cradle, as the centrifige ramped up, it pivotted out to the horizontal plane thus the "G" force was aligned along the vertical (now horizontal) axis of the lamp, same as happens in a nasa centrifuge for example, just smaller.
As an Atheist, this phrase "God is Dead" on a t-shirt, is SILLY, it is just as silly to me as religous beliefs themselves.
For God (any god) to be dead, god must therefore have existed at some point to have died.
As an atheist, the preponderance of evidence (or more, the preponderance of lack of evidence) is an ample justification for not having a belief in there EVER having existed a god.
