Hovering Card Trick: Explained

Watch these:



The secret invisible object illustrated in an MS-Paint-created picture:
secret invisible object in the hovering card illusion
The lines in red are the invisible object. The red dot is a joint enabling the shorter part of the object, a string, to freely move around.

First video. At the beginning of it, you saw that the card kind of levitated. Then you saw that it was an Ace card. That side was what the invisible object was directly attached to. The string was connected to the bottom of the card over the card, thus when the illusionist moved his hand forward, the string lifted the top of the card, making the card look as if it was levitating.

Second video. When the illusionist's palms were covering the card, the string was between the index finger and thumb of his right hand. He used his index finger to move the string to his left, which slowed down the spin of the card, thus causing the need to stop the card and spin it again. Then the illusionist used his thumb to move the string to his right.

Having them explained, what about another video by another person?

This performer began by taking a stack of cards out of the pre-cut card case which allowed a stringed card to go into and out of the case. Then he picked the first/top card which is attached to a string. Similar invisible object was used. Only this time, the other end of the object was not connected to the person but to something not shown in the video, to the left of the performer.

Why left?
- His first move had his arms moving over, below, in front of, and at the right side of the card, but not behind or at the left side of it. So, two possibilities left.
- His second move had his right hand pushing upward the stick-like part of the invisible object, while the string was between his index finger and thumb. Two possibilities left.
- His third move was an attempt to make you believe that he had covered all the sides of the card. But if you look closely enough, you'll find that he never covered the left side. It wasn't even shown in the video what he did with his left hand while he was moving his arms and the sword around the card. One possibility left--the left side!


Trick explained.


YouTube does have many other videos on this kind of card trick (most of them used cards with strings connected to the top). It's easier to perform such kind of card trick through YouTube, thanks to the poor quality of the videos that makes invisible objects even more invisible.
