A weird as this question is, I'll answer it for the points; though keep in mind that this will most likely be deleted.
Looking at this question from a scientific point and replacing it with a piece of paper instead. Depending on the ankle of the flick and the speed you would get every far. You have to take in account of where the wind is blowing that day, you muss also think about anything that could be in its way (the nose, objects, etc.) Then there is also how heavy or big the object is...
So in conclusion this is a odd questions and has no actual answer, but thank you for the points.
