Mysterious fold by Zoen's

The effect is strange and at the same time amazing
The one where we fold one card in half and then the strange thing is that we can pull the fold up as if it were loose and cut...
And when we snap our fingers the fold returns and is intact as before,
and the spectator can also examine it...
