Step 1: Materials
All you need is two aces and a seven.
I used jokers that I put stickers on them that say this, that, and other, you can make them if you want, but I'm not going to explain now. If you want to know how to make them just ask me and I will send you instructions.
Step 2: Double lift
Use an entire deck while practicing.
1-Hold the deck like you are dealing the cards out.
2- Grab the first card, while doing this also grab the second card.
3- Flip these cards over, but try to keep them together and not show that you have two cards.
4- After showing the second card, pretending its the top card, flip them back over.
5- Practice until good enough to show.
Step 3: The glide
2- Slide the bottom card back with your ring finger and pinky finger.
3- Slide out the card second from the bottom pretending its the bottom card.
4- Slide the bottom card back into place.
