Head Off by Mario Tarasini

Halloween is coming.
On this occasion, I present to you a scary trick - "Head Off..."
It will surely please the tellers of creepy stories.
The magician shows two cards - one card with a picture and the other with a hole.
The magician places a card with a hole on the picture, and the head in the picture suddenly starts following the hole...
The magician returns the head to its place...
The best part of the trick is that the cards can be given away as a souvenir.
They are completely gimmickless.
For the trick, I recommend coming up with a creepy story...
So, my dear mortals, grab the effect now...
