How to Do the Key Card Trick.
With this simple technique, you'll always
be able to find the right card and look like
a mind reader.
You will need A volunteer and a deck of playing
cards.
Step 1.
Have the volunteer shuffle the cards, and
then choose one.
Step 2.
Ask them to return the deck, and turn your
back so you won't see their card.
Tell them to remember what it is.
Step 3.
While your back is turned, look at the card
on the bottom of the deck and remember it.
This is the "key card."
Turn back around and have them put their card
on top of the deck.
Step 4.
Ask them to cut the deck, so that their card
is now in the middle.
The key card will be the one to the right
of their card in the face up deck.
Tell them to cut – not shuffle – the deck
as many times as they like.
The key card will remain next to their card.
Step 5.
Place each card face up one by one.
Stop when you get to the key card and bet
the person that the next card you flip will
be theirs.
Swear it's because you've read their mind.
Did you know Yale University’s rare book
library includes engraved German playing cards
from the fifteenth century.
