JUMP BICYCLE GAFF CARD MAGIC TRICK

A card, chosen or not, and a hole punch!

Take the card and using the hole punch, make 2 holes, 2 well separated holes.
Ask your spectators for keys, and take a small carabiner out of your pocket.
If your spectators do not have keys, show that your carabiner has one and that you can very well use it if your spectators wish!
Now take the card, pass the carabiner with your key (or that of a spectator) through one of the two holes!
Show the whole thing to your spectators, up close, very very close…
TRANSPOSITION!!!
Ask your spectators to look at the carabiner with the key hanging… tell them that this one, with the key, will jump from one hole to another! And all this in VIEW of course!
Needless to say, your spectators won’t take their eyes off the card and the key!
ONE TWO THREE…
The carabiner jumps as you just said on the other hole! It’s crazy! You have to see it to believe it…
How, carabiner and key can jump from one hole to another? A real mystery for your spectators and even for a magician believe me.
Finally, you remove the carabiner and return the key to its owner if necessary!
The card will end up in the trash; there is definitely nothing to see.
