1.It shows the human reaction time.
2.It shows the reason why we need to prepare some 'safety time' and 'safety space'
3.It shows a brief idea of Newton's First Law(Inertia).
Why is it so hard to grip the thousand note even it is just between our fingers? This is because from the moment you see the note falling to the moment that your fingers really start to move, it takes 0.2 seonds as reaction time. However, in this 0.2 seconds of reaction time, the note has already falled for 20 centimeters. This is why it is so hard to catch it. At that time, if your hand can move downwards for 20 to 30 cm and then start to grip, may be it would have a higher chance of gripping the note.
(Don't know the special term for that seond sentence)
