heres a reallly cool trick:
1) Get all the DIAMOND cards and line them up from Ace to Ten (Ace, 2,3,4 etc.)
2) Put these at the bottom of the pack
3) Ask a spectator to pick a card from the deck (hopefully not from the bottom
)
4) Tell them to put the selected card on the top.
5) Now CUT the cards (as in grab a chunk of cards and move them from the top to the bottom of the deck. DO NOT SHUFFLE ONLY CUT)
6) Observe the bottom card. when u get to a Diamond, for example a 6, say to the spectator, "Whats 3+3?"
They will say 6
7) Count from the top 6 six, the 6th card should be their card
Note: Just so u know, the "top" of the deck is when the cards are face down and the bottom of the deck will show the face of the card
Let me no how this trick works for u, try practicing in front of a mirror so u no how the other person will see it
