Inertia: Penny In a Cup

If you found getting a penny to balance on your finger to be a bit too challenging, this might be more your speed. 

Place an index card on top of an empty cup.  Set a penny in the middle of the index card.

Flick the card out....

...and the penny falls into the cup (the cup is a much larger target than your finger!)
