If you want to explore magic and need a basic trick to amaze your friends, a simple mind reading trick will do. I will go through the steps to help you understand the trick.
Step 1: Preparing the Trick
To start, take the deck and cut it, with half in each hand. Then causally glance at the bottom card of the deck in your right hand. This is your "key card." Make sure you know what it is.
Step 2: Prepping the Cards
Once you have done that, have a friend pick a card from your left hand and memorize it. Have him/her put it on the top of the left hand deck. Put the right hand deck on top of the left one, making sure the the "key card" is directly above your friends card.
Step 3: Finish the Trick and Amaze Your Friend
Flip the deck face up and begin looking through it. When you see the key card stop. The card right before the key card is your friends card. Reveal it and show it to your friend. He or she will be amazed!
