It's time to learn The Vanishing Deck ...
A deck of cards vanishes right underneath their eyes! Take a good look at the two items supplied. You are provided with a black shell and a trick deck of cards which is hollow and has a black shell interior.
Show the black shell and place it on the table with the hole facing downwards. You then show the deck of cards (shell) and you can open the flap and remove the playing card. It is an illusion. Telling people that you have a full deck of cards. Be careful not to flash the bottom of the card box shell.
You then insert the card box into the black shell. Making sure you place it in so that when you turn the black shell over you cannot see anything.
Done quickly the tricky box of cards (which is not really a deck of cards) will look as though it has vanished.
