Card Trick: Deck Memorization

We have already learned how the phonetic mnemonic system [ For more on 'phonetic mnemonic system' go here: http://www.braingle.com/mind/213.html ] can be used to remember playing cards [ For more on 'remember playing cards' go here: http://www.braingle.com/mind/241.html ]. Once you learn this, here is an interesting trick that you can perform for your friends and family.

Deck Memorization
Have your friend shuffle the deck. Now, go through the cards and use the link system [ For more on 'link system' go here: http://www.braingle.com/mind/19.html ] to link each card to its neighbor. For example, if the ten of diamonds (keyword=dice) is adjacent to the two of hearts (keyword=hen), you could form a visual association of a hen laying some dice instead of eggs. With practice you should be able to go through the entire deck in a few minutes. Now you can recite the entire deck from memory by going through your link list and remembering the keywords.
