Colour Changing Card Trick


Hi, I am Richard and this is Sarah, and we
are going to perform the amazing colour changing card trick with this blue backed deck of cards.
Now the idea is very simple, I am just going to spread the cards in front of Sarah and
ask her to push any card towards the camera. Right ok, let’s see, I am going to go for
this card here. OK, now Sarah could have selected any card
at all from the deck, but she selected the card which is now face down on the table and
what I am going to ask her to do is show us which card she selected.
Right, so the card that I chose was in fact the three of diamonds.
The three of diamonds, ok, excellent choice, that card goes back into the deck. Now I am
going to spread the cards face up on the table. give a little click of the fingers and you’ll
see that Sarah’s card here has now got a blue back. Not particularly surprising. What’s
slightly more surprising is that all of the other cards have got red backs. And that is
the amazing colour changing card trick. Hi, I am Richard and this is Sarah, and we

  1. Thank you Professor Wiseman, I've used this together with the 'How many F's can you see in this sentence' to highlight the way we filter out information.

  2. I didn't notice the changes but i did notice the unusal camera movement that was hiding parts of the frame.

  3. On my work we are creating Apps. We recently discovered a bug which is very visible and frequently occurs, but has gone unnoticed for a long time: The font size of some text changes drastically and some figures changes color when the display updates. This is not supposed to happen but nobody have noticed. That is – until we started automated testing and the computer checked the display content for us.

  4. You know you've been watching this channel long enough when the background noises cue you in that theres something else going on on your first watch

  5. Wrong the card she chose had a blue back and so did the others but her card had always have a blue back but the other back became red.

  6. I did notice the color scheme of the room became brighter, but other than that, I was completely blind.

  7. What's the trick based on the same principle, where you have the spectator counts the cards the magician deals on the table and then "something happens"? (being vague on purpose for first viewers) Can't find the link, please somebody helps.

  8. I knew that it was green screen when I saw the red background

    Edit: wow I was wrong I was writing this during the video
