I begin by asking a member of the audience for some coins to
use for magical purposes.
"Just bring out a handful of change," I ask,
"whatever you have in your pocket."
Then I look the coins over. "You don't have any gold
doubloons," I notice. "Never mind. I can convert them
using the Gringott's Bank ATM."
I then bring out an empty cloth or leather bag with a string
closer top. On mine I have large letters A.T.M. "Sure, this
is my ATM... Always Trust Me. Drop your coins in the bag."
The spectator drops his handful of change in the bag. Wham! I
slap the bag on the table and then make the coins jingle. Then I
dump out the coins and show that I have four and one half gold
doubloons. I pick up the half-coin "That's because of the
Fair Exchange rate. Money isn't worth what it used to be worth
Now I go into a Han Ping Chien "coins across" with
the gold coins and the half coin. While I have Professor Kyva
visiting, I take advantage of his friendship by getting him to
pose for the photos to explain the Han Ping Chien variations he
uses to accomplish this effect.
Afterwards, I drop the coins back into the bag
and WHAM! hit it on the table again. This time I dump out the
original spectator's change into his hand and thank him for the
use of his money. I hand him a complimentary A.T.M. card to
remember me by, which, quite coincidentally, has my name and
phone number on it as well.
