longWe often get inquiries from people who want to use our Quirkology clips in talks, training seminars, and lessons.  As a result we have produced a downloadable pack containing 5 of the most requested psychology-based videos, including the world famous ‘Colour Changing Card Trick’. Purchase the pack and you are free to use the videos for talks and lessons (see terms and conditions at the end of this page). For a few days we are running

The five videos are:

The Colour Changing Card Trick: The well-known video in which 95% of the visual scene is changed, and yet most people don’t spot the changes. The pack includes 2 versions – with and without music. Neither video has the ‘created by Richard Wiseman’ watermark present on the YouTube version.

The Test: An example of inattentional blindness, with people failing to see what’s in front of their eyes.

The Afterimage: See a black and white video in full colour!

The Witness: See an example of ‘slow change’ and discover whether you would make a good eyewitness!

The Card: Discover how your expectations shape your perceptions!

The file is in .zip format, and contains all 6 videos when uncompressed. All of the videos are produced in standard definition, in a 4:3 aspect ratio, in QuickTime .mov format, and in English.


“I am one of the Advanced Interviewing Program Managers within the United States Justice Department, and incorporate the “Color Card Changing Trick” in all my classes to teach the value of active listening with your eyes. It’s awesome!”
Janine Driver, Washington, DC

“The Quirkology clips are a fantastic teaching tool – they always generate lots of interest, initiate insightful discussions, and provide a real contribution to the learning experience of our students”
Randell Siow, Victoria School, Singapore

“Our team loved the “color changing card trick”. It provides an excellent demonstration of how often we focus on a challenge and overlook the opportunities that are right before our eyes.”
Hannah Ellis, Vice President of Marketing, Promark Financial, Santa Ana, CA

“Wiseman has created the most convincing demonstration of change blindness that I have come across. It is a fascinating teaching tool that shows how unaware we are of what’s right in front of us.”
Dr Paola Bressan, Psychologist, University of Padua, Italy
