This is a great packet trick that I've done many many times, and it's always gotten me great
reaction. Four jokers are shown face up and one by one they are turned face down. In the end, the
cards are turned face up again but this time they are all aces. All four cards are cleanly shown
front and back. This trick is almost instantly repeatable. There is one small move you need to do
but nothing hard. Eventually the gimmick may wear out but you can easily replace it.
