I will tell you my prized card trick. Someone at school showed it to me and didnt tell me how to do it but I figured it out.

All you need to do is look at the bottom card. Tell them to pick that card. Then look at that card. Tell them to pick that card. And once more. Then say you will pick that card and pick the bottom. It would be like this.

The 7 of clubs is on the bottom. tell them to pick the 7 of clubs. They pick the 5 of diamonds. Tell them to pick the five of diamonds. they pick the queen of hearts. Tell them to pick the queen of hearts. they pick the 4 of spades. say you will pick the 4 of spasdes and take the 7 of clubs off the bottom. Then show the cards. Yay!
