I feel it should be called Ghost Handkerchief.
It's really easy and since the instructions
aren't in English - here's the fun way I figured out how to do it.
Audiences sometimes like
seeing magicians mess up - and this is a fun one where I purposely tell them I haven't performed
this in a while and if I mess up when naming their card not to tell me the name of the card & to
give me another chance.
An audience member selects a card (via a force) - shows everyone I
then tell them to shuffle it into the deck and lose it. I purposely mess up in naming the card (I
already know the card since it was forced) & told the group (which had some kids in it) that I have
a handkerchief which is haunted and that the friendly ghost inside helps me out when I need it.
I say taking a picture with the phone helps wake up the ghost - so, that's why I need a borrowed
phone. And then after I take the pic and guess the card correctly they're impressed - but as I
return the phone to the spectator - I say - "Remember, it wasn't all me - the ghost helped out as
well," and show them the image on the phone. That reveal played really big as everyone wants to
check out the phone and is in awe.
In a fun way that picture is a takeaway for the
audience member as well - as it's on their phone.
Really the only thing you need for the
trick is an audience member that has a phone with a flash on it - which is pretty standard - but
imperative for this trick.
This trick is good for magicians of all ages - and is easy to
perform. The only skill you truly need is to be able to force one card - there's a ton of ways to do
that so pick your fave. The handkerchief also has some mentalism abilities with an arrow - but I
haven't thought of what to do with that yet.
It's an unusual trick and a fun one at that.
