You will need a stack of coins to perform this trick.
Effect
Catch a stack of coins as they are falling from your elbow.
1.
Stack a pile of large coins on
your elbow. Prepare yourself mentally to catch them as they
fall.
2.
Let the coins to drop down and
whip your arm down swiftly and grasp all the coins.
You can also make this trick a bit easier for yourself by
throwing the coins slightly upwards instead of dropping them
downward directly. This way will give you more time to prepare
the catch but the effect is not as spectacular as the drop
and catch motions.
