I remembering doing this when I was a kid, We use US pennies as they were the smallest. lol

Coin snatching, often nicknamed the Chinese elbow trick, consists of a simple illusion in which a coin is placed on the elbow, the hand of the same arm is placed on the arm's shoulder, and the hand is swung forwards to catch the coin. The trick can also be performed with a stack of coins. If performed correctly with a stack of coins, it will appear that they have teleported with a bang.

Science behind Coin Snatching
Since the coin is still it tends to remain in that position. Good old inertia! When you elbow moves rapidly it just drops out from under the coin. This leaves the coin hanging in air. Gravity then pulls the coin towards the ground, but inertia gives it a slow start. Your hand is faster than the coin because your hand is already moving. So once you practice you should be able to catch many coins.

A world record of 328 coins was set in 1993 by Michael Torres (Eastvale), in accordance with British rules which specify that coins must be 10g or heavier (ruling out US quarters), that they may be arranged in multiple stacks, and that the catcher is allowed to drop some of the coins, counting only those that remain in the hand.

World Records for Coin Snatching
The Rules
1. The coins are to be placed on the elbow.
2. All coins must be caught in one snatch and the snatch is to be achieved on a downward beat of the same arm and the coins caught palm down. If not all of the coins which are stacked are caught, the attempt is still valid, but only those which are caught would count. In this instance, the documentation should mention both the number of coins stacked and the number successfully caught.
3. Once they are ready on the elbow, the coins are not be touched by the hand which is not being used to catch them.
4. No adhesive of any sort may be used.
5. The coins to be used are 10 p coins in Great Britain, or in other countries coins weighting at least 10 g (0.35 oz) and having a diameter of at least 2.8 cm (1 1/2 in).
6. The record is for the greatest number of coins caught in this way.

The Records
The first records in this table were achieved with coins in a single column, which makes the attempt much harder.

Some claims from Canada and the USA did not count for the purpose of this record list, because the used 25 US-Cent coins were too small. catching coins off your elbow kids fun science
